Ok here we go. My car idles between 1k and 1500 rpm's when warmed up. If the car sits and idles long enough and doesn't drive anywhere after about ten minutes the check engine light will come on. Once the car is off and turned back on the check engine light doesn't come back on. So my friend and I cleaned out the fast idle thermal valve and the idle air control valve. Still the same problem occurs. Please help. I have ngk plugs with msd wires and a walbro 255 fuel pump and aem cold air intake. Those are the only mods done. Not sure if that will have anything to do with it, but please someone help me. Sorry this is so long. Please help I beg of someones help.
