I have a 2.0 non turbo that has idle problems. Since buying the car it has always idled high, around 2,000 rpms. The exhaust would glow bright red at the end of each race(10 laps around dirt track).So I upgraded to the bigger blue fuel injectors. It helped the glowing exhaust but made the idle problem worse(3,000 with idle screw all the way in.) I changed the iac with another(used)one but no differance. also changed the tps with another.no change. However if I unplug the airflow sensor The idle will drop to norm and run a little rough but still tacks up good. I can not figure this out, can anyone help?
