if you mean the air temp sensor for the MAFT Pro, it richens it up a bunch.

ill be replacing my ISC in a few weeks... along with the rest of the engine! lol

A vacuum leak doesn't affect the idle tune....... but it will affect the idle
speed

edit: it's between 30 and 45 degrees out there when I do this.

had that same problem, and i had to add fuel. ever since i added fuel i have no longer had that problem.

How much fuel did you have to add? 5%?

not to sure, but i think it was around 4-5% in the mainscale. basicly i just added fuel untill it idled well and i had a good af ratio

runner4053 · 01-11-2006, 07:50 PM

Well, I can get it to idle right now. It's set at +6.0 mainscale on stock injectors.

1.) Start the car
2.) wait for it to come off of high idle
3.) it starts cycling between 300 RPMs and 1200 RPMs
4.) Blip the throttle a few times and it holds steady at 900ish
5.) After some reving though it can be coaxed back into it's cycling.

YAY for step 4!!!!

Now just to figure out how to get it not to require playing with the throttle to get it to idle and getting it to stay steady.

check the connection on the tps tap at the ecu. i believe rustang had a problem with that and was causing weird problems. he soderd the tap instead of the t connector and problems went away. look into that maybe.

What are your trims reading?

Guess what, mine is doing the exact same thing right now. I just started it tonight after a bunch of upgrades and it started doing this too. I am not sure that I dont have vacuum leaks though. I just started it to make sure my upgrades didn't break anything and I am installing an AEM sometime soon (so my maftpro will be for sale soon)
