The tbird finally got a shot! And now a 2nd one!

Basically with the IAB disconnected you need to set the idle to 700-800 engine HOT... At that point verify the TPS voltage (.85-.9v is fine), adjust if necessary(needs to be a little LESS than 1v, or high idle will result)... Reconnect the IAB and you're finished...


May be a good idea to disconnect the battery to erase the EEC's memory...

Thanks a bunch for the info; hopefully I can get to that tomorrow since I'm off work.  And yes, the car seems to like 750-850rpms for idling (when it idles like that).  And the IAB is by the distributor, correct?

IAB is the thing by your throttle body with a electrical connector.

I just thought of something with your "*NOS* in 3rd". Did you change the stock fuel pump out when you did the swap? If not the stock pump could be playing catch up to feed the engine. Mine did something like that when I took it out the first time after the swap. I put in a 155 l/ph pump and it stopped. I left the stock pump in just to make sure the engine worked then I swapped it out:hick:

Nah it's still the stock fuel pump.  Trust me, if she's low on power in 1st and 2nd, then the stock HO must be a MONSTER.  The car still pulls really hard.  I think dad said he felt her lay down around 5400rpm, which I will never push my car to anyway; she pulls strong to 5 grand, which is fine for me!  But yes, I'll be upgrading that soon anyway.

Well with a 3.73 gear and the stock tires mine will spin the tires with anything over 1/4 throttle from a stop. This, while it sounds cool, can be annoying at times :hick: . With the better cam/heads I have the engine wants to rev well past the 4,800 rpm shift point of the stock AOD. Me thinks I need a shift kit, better exhaust (2.5" pipe) and a better intake. Oh and probably a 2,400 rpm stall converter. Have you bumped the timing from the stock 10* BTDC? I had mine at 10* but when I hit 400 miles I bumped it up to 12* and it really liked that. When I hit 500 miles I'm changing the oil and bumping the timing to 14* and if it doesn't ping 18*. It has to run 93 octane because of the 10:1 compression so I might as well get some extra power by bumping the timing:D

Triing to kill that motor already?  18* is WAY overkill, most 5.0L dont like more then 14*  MAYBE 16* tops, I bet you wil only experience hard starting and major pinging at 18*

No, I'm not bumping the timing.  There's NO WAY I'm putting premium in it....it's my DD!!  Many people forget this fact when giving me ideas hahaha.  I'm more than happy with the power I have.

And btw...the HO is a PAIN when it's raining.  I was sitting on a hill at a stop light and when I went to move, she just spun the tires.  Ugh Im glad there wasnt a cop there.

Oh I wasn't going to go past 14* really. I know a buddy with a 5.0 Stang and it really liked 18*, but every motor is different. I might try it once but it's waaaay overkill. It seams to like 12* fine but in a week or two I might bump it to 14* at the most. I don't want to worry about pinging if I end up having to use 91 octane in an emergency.

You *might* be able to bump it to 12* on 87 octane. Some people have been able to do it some haven't. Every motor responds different.

Well for now, especially with the kind of gas mileage I've been getting, I'm leaving it as she is.  After the exhaust, a new fuel pump and fixing that bog problem are first on my list.

Interesting.  Any difference in gas mileage?

my first "drive of the lincoln was in the rain, after 2 years of not running, and no tune up, still raped the tires out the driveway!

dunno yet im keeping track of it. according to my digi-dash economy meter im at like 15.5 mpg. which doesnt make much sense to me. thats less than it used to be, which was always between 16 and 17. normal suburban area, a lot of 30 and 40 mph roads, certainly not stop-and-go. its been bothering me for awhile. but i tanked her up a few days ago, im gonna measure it over the next couple weeks, then knock the timing down and see what difference there is. according to the meter though it seems theres no difference, at least positive anyway :hick:

Yeah thats why I'd rather not touch the timing right now when my Tbird is knockin down 22-24mpg consistantly and has plenty of power for me.  Be sure to keep us updated.
