im messing with a friend of mines car, and its having some issues. when the car is fully warmed up, it idles perfect, stft hovers between -1, +1. low is 1, cruise is 3. BUT when the car is cold, you cannot keep the car on without keeping your foot on the gas, it will not idle on its own, and then as temps rise and its up to operating temp, it instantly turns to a new car, idles like mentioned above.

this is an evo8, precision 1200's on e85.

any ideas?

 

IPW adder, cold timing maps, etc

 

i am having a similar problem. all of a sudden, filled up gas and now i idle (when warm) @ 17.0 AFR via the WB.

before it was steady 14.7 or thereabouts.
