Well i'm new to the Ford world so i'm a little dumb on this.I changed my tranny in my bird witch has a 5.0 in it i went to a C6 Tranny.Well after the job was done i went to bring her home and found out that she won't idle and she is running way to rich.Mind you she ran fine before the tranny swop so i have no idea what the heck went wrong.
I've tryed everything and anything i could think of so now i'm so close to just burning it to the ground LOL.Although when i get her to go down the street when i stomp on her the power is right there but won't idle and is running way to rich i have done full tune up.PLEASE HELP.:beatyoass:
someone unplug the o2's while they were under there?
No there were no 02's on it and it ran perfect.I would like to get it running right cause it was one bad ass running ride.Although if i can not get it figured out i might just sell it and the system that is in it and find a diff v8 lol but i just love the way these birds look and besides my brother is building a monte carlo and now he is talking about it clipping my birds wings lol
It is fuel injected right?? if it isnt we need some more details to help you in this diagnosis
Yes sorry it is a 5.0 efi motor i have changed the fuel air controle valve i think it is called it is also killing the plugs super fast i mean put $30 dollars in gas to gomaybe 20 miles and it is empty thats how rich it is.
X2.What year is the car?Original engine?Carb or EFI?
You have to have O2 sensors.How about the FPR?
lol ok this is where the dumb part comes in to play what is a FPR?
Also this car with the tranny burnd up and stuck in 2nd gear still ran perfect and would do a 100.lol this car i have been working on about 5 months and it is getting sad:mad:
Fuel pressure regulator=FPR I think vin is saying maybe your fuel pressure is out of wack
if there is no O2 sensors in the exhaust it will screw up the computer big time.
ok but my question is there were no 02's before the swap and it ran fine but with the swap somthing could have got bumped so how would i check or fix this FPR?SOrry i'm so dumb lol
map sensor vac line could had been pulled off making it run bad.
you need to get some o2's in it.
If its fuel injected, there are O2 sensors. End of story.
ok i will check map but i have no books on this so can i ask where it is?
next to the vaccume tree on the driver side of the engine compartment
There should be two O2 sensors on the car.If your car has stock exhaust manifolds,they should be on the back of them,screwed in with small harnesses coming off of them.Perhaps the O-2 harness was unplugged.Did you remove the TV cable?
ok see this is where me being new come's in to play lol the o2's are on the manifolds i thought they were like GM on the cross over pipe thats why i said no but i will go out in the snow right now and check these things brb.As far as disconecting the TV cable if you mean kickdown cable yes it is gone cause i went with a after market B&M shifter.
First off let me start by saying WOW WOW WOW this site rocks.I followed what everyone said starting with vacume lines connected any that were not connected.Started the car still no go running rich and not idleing.So i tapped on the fuel reg and looked for the map sensor to check plug well i found it and what do i find????A vac line not connected to the map so i hook it up start the bird and she purrs again no smoke idle's on her own smooth as a "BABY'S BUTT".So thank you to everyone that help i'm hooked to this site now TY:burnout:

Your motor SHOULD resemble this if EFI.....You most likely don't have the MAF though;)
