I did a basic coil test by removing the coil connection one by one to see the change in the idle. I noticed two coil packs that did not respond. So, I purchased two coil packs from my local AutoZone, replaced them, and guess what?
Still the same problem. The coil packs are fine. What's next, the injectors maybe? Now I gotta return those and get either injectors, or something else. Any info you folks have would be invaluable, Thanks.
