Hi,
Got a 1996 dodge ram 1500 4x4 5.9 litre Magnum V8. Check engine light on, codes were engine misfire in 6 of the eight cylinders and idle air control. The truck is running fine, slight miss. I am putting new plugs, wires, cap and button. Should fix the misfire code. But there is no idle problems. Truck starts easy, runs with no surges. You think after I tune it up tonight, the idle air control code will still come up after I reset the ecm? I guess it's a dumb question but anyway.

Thanks for the reply. Just got finished with the tune up//no check engine light. Oh my god, changing that cap and button and plug wires was a terrible chore. Plugs were rusty, and there was not much left of them. The truck did do something weird though. When I tried to start it after all was said and done and resetting the system, it wouldn't turn over. I turned the key and it clicked. Finally after turning the key a few times it fired right up. Idle fluctuated a bit, but after about 20-30 seconds it was purring like a kitten. Drove it and it is smooth, with lots more power. After test driving it, I shut it off and it started right up. Gave it a few minutes started right up again. I don't know what the glitch was but all seems well. Thanks again for the info.
