Hey my CEL threw a code 14 and a code 43 ... 14 being IAC and 43 being Fuel Supply system...Hm ok here it goes when I have my IAC plugged in...my RPM's surge between 1500-1800 very fast but as soon as I unplug it it has a strong idle at about 900 but on that note to when its not warmed up the rpm's will drop to almost 0 while driving (when its not warmed up) So what should I do with my IAC problem when I plug it in how the RPM's surge very fast so I need some help with that if possible and what does the Fuel Supply System code mean? thanks

you probably need an iac, and fuel system usually means a delivery problem. do you have an adjustable fpr? if so set it to stock clear the code and drive it.

No I dont have an adjustable fpr so I dont know about that how much to IAC's run for?
