When the car is cold, it won't idle correctly. The idle just goes up and down, the car will shake very BAD. Seems like the ECM is searching for the best idle, and this all happens in open loop. Once the car is in closed loop it doesn't have a problem idling(But, the motor will shake and miss a little). Also, at steady throttle going down the freeway say 80MPH, the car stutters, shakes and even backfires through the exhaust. I replaced the plugs, Set TPS to .42 key on and IAC 13% ,changed O2, new TA49 turbo, new Blue tops, cleaned IC, cleaned IAC, removed intake and cleaned EGR passage, and still no luck.
I am running an emissions chip (TRYING TO PASS CALIF. SMOG) for the Blue Tops that Joe Lubrant burned for me. (I had this problem with the Stock chip with Stock injectors as well.)
I have Turbolink and all numbers look good.
My idle blm'S are fine, about 120.
My 02 cross counts are moving good.
HELP...
