When I start the car up the idle is high and keeps rising as if I',m feeding it gas. I',ve checked the vacuum lines and they all seem good. could the IAC sticking or going bad because this?

iac can because it but the most probably because is a bad throttle position sensor on it,run a scan on the computer for trouble codes,see what you get from it,good luck.

thanks,i hope this helped out some,good luck with it. Report Abuse

Either a dirty throttle valve or the fuel line is dirty and the engine isn',t to get enough air to gas percentage. If the fuel line is dirty then that means the tank is dirty and will have to be cleaned out and a new fuel pump installed.
