Well there's your problem
Hey guys old user new name. I have a 94 lightning #3585 I'm trying to get running after sitting for a couple years. I have just replaced the infamous IAC and it idles again! My question is, it still surges a bit every now and then, and the exhaust steams even on warm days also smells like fuel real bad. Any ideas what would be causing this? Could it be tps, egr, or just the CPU still relearning the idle?
