i just swap a b-16 into my hatch. when i start it up it runs perfect when its cold. after it warms up the idle drops from 1k toabout 200 rpms i've done everything i could think of. if anyone has a clue or even had the same problem please give some suggestions.

 

I was under the impression thats a good idle?

 

Thats too low? Have you try cleaning you idle air valve? and what is the idel when cold?

200 RPM is kind of low.

hm...did you try adjusting your idle screw?

 

i was tired last night. i ment to say that when its cold it idles at like 1200 to 1500 rpms. when it \s warm it drops from a 1000rpms to 20orpms then back up to a 1000. some time it stalls. i put a type r intake cam, manifold and throttle body on it,. i'm throw just the o2 sensor code and i just recently threw the knox sensor code
