Hey guys whats up i have a b20v semi built. driving to work this morning the CEL came on and the car started to idle real low like its gonna shut off. But if you keep your foot on the gas it will stay on. I have Hondata S200 so i cant read the code on my own any news of what might be causing the problem? Thanks in advance.

 

Your IACV probably needs to be cleaned. Or it could be your IAT sensor or your idle positioning sensor. What I did was trial and error. Replaced all of those.

 

I need to find what the CEL is but thanks for the reply.
