My cars been running like its out of gas at low rpms, and I just threw a IAC code 14 last night. It stutters real bad and its driving me nuts. I recently replaced my IAC valve because my idle was horrible and it worked for a couple weeks, and now its just stuttering.

Any ideas? I havent had the chance to take off my IAC again, but if its not that anything else?

 

Did you get a new IACV? If not, check if it's clean (the valve will be white inside), and if it's not, clean it with carb cleaner. If it's new, it may just be bad or your wiring could be bad. Follow the check procedure in your repair manual (if you don't have one get one ).
