I swapped my fuel injectors and my FPR,buttoned it all back up,now smoke from the exhaust.I let it run for a few minutes,still smoking.I installed an extra set of injectors I have,still smoking.I re-installed the injectors that I had in it before all of this,and re-installed the FPR,still smoke.What the ?!!! I've never had smoke coming from my car.The plugs are black.Dry,but black.I could smeel a strong odor of gasoline from the exhaust.I'm wondering if gas got in the oil.
I'll check the dipstick.
The oil has just been changed (was afraid I may have dumped too much gas in the engine and got fuel in the oil).Still smoking.There's dampness on my exhaust tips.Oil/fuel?It's not water,and it doesn't have a lot of odor to it.I just checked the oil after getting home,looks great.I checked the plugs,they have a dry reddish-brown color to them.None of them are wet.Perhaps there was fuel in the oil,and the smoke is from whatever is moist in the exhaust burning out.I have no idea where this smoke is coming from (what is causing it).I did change the IAC yesterday,but re-installed the old one until I can pinpoint this problem.As I stated above,this engine has never smoked.Not until I tried to change the injectors and FPR,which,are off the car and the old ones are back on again now.What could it be?
Did you forget to hook up your Map sensor?
Yep,it's hooked up.Everything is hooked up.I'm hoping it's just residual in the heads/exhaust burning off.I am lost on this.I'm not losing coolant,no water or anything else in the oil.Something is causing the smoke.I'll drive it around and see if it goes away.Any more ideas?I'm lost.
Run some seafoam through to really clean it out. That would get rid of stuff burning off of the heads/exhaust. What color of smoke is it?
pcv hooked up and not clogged?
PCV hooked up,the smoke is white as can be.I'll go ahead and get a new screen to install under the pcv valve.I am going to let it run for a while tomorrow and see what happens.I think too much fuel.Just my thought.
i think if it was running rich, it would be black smoke. white smoke usually means water is getting in the combustion chamber. bluish-white smoke is from oil.
I may be over-looking something but...
Are they different rate injectors or just new replacements?
What was wrong with the old ones?
What about the FPR, is it a stocker?
They were replacement 19# injectors.The FPR was an adjustable unit.Since the fuel pressure gauge that I borrowed didn't work,I couldn't tell how much fuel I was passing along to the injectors.When the white smoke was pouring out of the exhaust,I could smell gasoling really strong.If it's water,that would be a really big coincidence.Too big.I'm going to work in a few minutes and I'll see what happens now that everything is back as it started.If,for some strange reason,I do have some water getting in the oil,that's O.K.,it would probably be going through a head gasket and that would give me a reason to get the new heads on the car.BUT,I really don't think that's the problem..................or is it?
well, that being said, your gonna need a f/p guage to dial in 40psi.
On the CFI units, one full turn equals about 2psi.
if it isnt just right, it will smoke ,, but the color of white,,, not sure what you did if it didnt smoke before.
bypass / loop back the intake cooling lines and see if that makes the smoke go away. Thats an easy way to see if the upper intake is cracked anywhere.
The intake cooling lines (going through the throttlebody spacer) never have been hooked up.I'm going to go ahead and replace the pcv valve and the screen just in case.On the way to work,the Sport smaoked a little,but on the way home,I didn't see anything.I hope this problem goes away quick.It really doesn't make sense to me.I've een through EVERYTHING with this car.I think she's (the Sport) testing my loyalty.The blue car did that..............it's a parts car now.
Any update?
O.K.,update (sorry,I should've did a follow up).The car isn't smoking anymore.I think that I dumped WAY too much fuel into the engine and it mixed with the oil and was causing the engine to smoke.I really can't find another reason for the problem at all.I'm going to re-re-install my new injectors and once I get a new fuel pressure gauge,the adjustable will go on......if I don't decide to sell it first because i want some other parts.But,no smoke.On another note,my heads should be ready for pick-up in the morning at the machine shop....finally.
By the way,Demon,is your car Mass Air?
yes. I may be experimenting soon though.
Just wondering.I will be converting eventually myself when the bigger upgrades start.
Hey V8 what does that mean?

I'm curious to see how SD runs with a TFS stage 1 cam. I want to see it first hand.
Let me know.I need a new cam.I'm unsure what to get with Speed density.I was going to contact Comp cams and see what they say.Do you have any ideas?
Take your pic!:D
FMS M-6250-B302 is a SD friendly cam. another version of the "B" cam, but shorter duration.
It will run like poop... My TFS Stage one idles approx 11" vacuum, speed densety is going to be real unhappy with anything less than 16" or so... May can idle it up to get more, but then the SD is expecting even higher vac...
Something that should work, is a vacuum pump or maybe just a reserve tank(a large one) with a throttle controlled regulator... The 80s GM diesels used such a setup to control the vac for the modulator valve on the 350 Turbo Hydramatic transmissions... It worked really well, I had one in a Cutlass...
Tom
Comp 266HR cam (#35-308-8). That's what I use. It runs great with SD but it's close to the edge. You might have to bump the hot idle when not in gear to ~1050 rpms (~850 rpms in gear). If you don't you may have trouble when shifting from park to drive (it might stall). Cam specs are 210* intake/215* exhaust with .533/.533 lift with a 1.6 rocker. It has good low end torque and pulls like a mofookie above 3,000 rpms. It does not fall off above 5,000 rpms either like the stock HO cam:D

First cam on the list under magnum efi cams:D
I GOTTA get me a new cam.My car runs really great,but,I need a little more.You know what I mean?
Sooooo if you have a "B" cam it's Mass Air time then eh?
Mmmmmm.......could be.I got the cam that 32FoxBird reccomended.I was told it's great with Speed Density.After I get the heads and cam on,I'll start collecting everything for a Mass Air conversion.With the cam I also got a gear drive timing set as part of the deal.I don't know if it's going on or if the new timing chain is going on.I still have to gather gaskets and fluids for the parts swapping I want to do.Gotta sell more stuff first.My monthly allowance for the car is already depleted.
Mass Air?Probably this fall.I got the cam 32FoxBird spoke of above,and as part of the deal,I'm also getting a gear drive timing set.I may or may not use the timing set,we'll see.I'll start gathering Mass Air parts soon.I still have to get gaskets and fluids to install my heads,cam,etc.I'll sell some more of my extra parts to get this all finished.
Hey Thunderjet,do you have Mass Air yet?How hard is it to install?
Nope still SD. That's why I used the Comp 266HR cam.
did you get the b303 or the b302? the b302 works better with SD. as far as mass-air conversions, its real easy. get a mass-air pigtail from any ford eec-iv vehicle, buy some 18ga wire, get a mass air meter from a v8 fox mustang and computer, then look on the net for converting. there are diagrams that show you which wires to tap into, and which pins to move on the bulkhead connector. this is the way i did, and running 19lbs injectors with a SD cam and computer netted a failed emissions test. the next day i converted to mass air only, and it passed with flying colors. still using the SD cam.
It's the 303.Do you think it'll work with Speed Density?To be honost,I thought it was the 302 when I bought it,but,my fault for not paying close enough attention.I'll start collecting the Mass Air parts I need as soon as I can.I've got to sell my extra parts and get this project going.I want to get my engine done and the Mass Air finished before I get the car painted.
With the B303 you'll need Mass Air. It just won't idle right with SD because of the lobe separation angle.
Ford Racing states all of the alphabet cams require Mass Air...
O.K.,Mass Air will come sooner.I saw an '89 Mustang harness on E-bay,but I think I'll get the kit and modify my extra harness for the Sport that I have.OR,do you think it would be easier to modify the harness while it's in the car?I want this to be hassle free.....as much as it can be anyway.
Vinnie all you need is the plug with a little wire from the maf.The rest is just adding and moving a few wires to the comp.It's not as hard as it seems.I seen the plugs goin for .99 on ebay.http://cgi.ebay.com/ebaymotors/MUSTANG-88-87-86-MASS-AIR-CONVERSION-PIGTAIL-MAF-5-0_W0QQitemZ330141362142QQihZ014QQcategoryZ33557QQrdZ1QQcmdZViewItem
Or just get one from the yard.
It ain't a big deal, involves just seven wires(maybe nine)... Four added for the MAF meter, two moved for the TAB & TAD solenoids, and one added for the fuel pump monitor... Last three aren't even absolutely necessary... The Ford Racing piggyback EEC connector that is supplied with their MAF conversion, doesn't even address the last three... Cars using it, spit out all sorts of codes...
The '87-earlier harnesses lack the two wires for the speed sensor, had to add those to the harness I used...
I would NOT pull or replace a harness to make these changes, far easier to modify the existing one...
For the TAB & TAD, I added the pin connectors to the EEC Plug, and just tapped into the wires to the solenoids leaving the pins for SD in place... Technically mine is setup to run either MAF or SD(and not throw codes), did same on a stock Stang years ago...
It sounds easy to you guys,but that kind of wiring makes me nervous.I can swap engines,suspension,interior,do bodywork,just about anything,but,when it comes to electric fan wiring,and this Mass Air stuff,I don't trust myself.I need a diagram with a few pics and an explanation that a first grader could understand.....and I'm serious.
Also,if I just buy the plug,I'll need the small connectors for the computer,where do you get those,or,I could buy the kit for $39.99 which has the wires,plug,connectors and instructions.I also read that a harness from an '89 Mustang 5.0 will just swap in with no wire swapping or anything.Comments?
Vinnie cut any plug off of a car at the yard .I keep one handy,
Each wire comes out with a tiny screw driver.If you use that pic I gave to you it will show how easy.After you do it you won't believe how easy it was.Hardest part for me was gettin slack on the cables at the computer,and that was my own fault .Tired from replacin the moter and exhaust and the wireing in 2 days.
I will mail you all the wires to plug into the comp if you want.
This cake for you BUBBA!
Sweet.I'll take it.I'm getting really excited about this converion.It may be a little while before I can get the cam in,but one step at a time.
I'm getting close to doing the swap.
