You removed the throttle body from the engine, cleaned BOTH sides, and had the battery disconnected for at least 35-40 minutes while doing the cleaning?

did you check the spacing on the spark plugs. if the spacing is off it can cause that, it happened to me.

Huh???

OP hasn't responded to any questions/suggestions, but it says "solved" on the thread title. Real nice when posters come here looking for help, get help, fix their problem, but offer no thanks for it.

Unhappy Po306

I was wondering if anyone has new information regarding PO306, my MIL is constantly on now. In the past it would show up occasionally, perhaps once every couple of months. These are the things that I did, swapped coils, put in the AC Delco Iridium 41-103 spark plugs, new air filter, removed the throttle body and cleaned it on both sides and pulled the two PCM fuses and waited 30 minutes. At that time which was a few months ago everything was fine. Other than the code the TB has a slightly rough idle, but has great power for a vehicle with 174,000 mi.
