Adjusted the IAC and set the idlescrew so we had about an 800 RPM idle. I thought maybe that was going to do it, but as soon as we turned the steering wheel -poof- idle drop towards 500 and it stalled. Had a heck of a time getting it started again. Engine had near zero power while running, we could barely get the vehicle rolling <img src="/forums/images/graemlins/frown.gif" alt="" />

Had my son pull off the alternator, going to bench test it tomorrow. I also found a thread today where someone's problem was similar to ours. Last post in that thread says he replaced ignition module and it was resolved!!!

I'm not sure what to try next. I bought an oxygen sensor and socket today, but haven't put it on yet. Started wondering if this is happening with a cold engine and we're not getting any codes - should this sensor even be in question? Can't decide whether to take it back and focus on other things...

Did notice that the pintle(sp?) was making a noise while resetting the IAC (while engine was off but ignition turned to on and waiting 30 seconds...), but read here somewhere that sound is normal while adjusting.

I'm also going to pull all the spark plugs tomorrow and regap them. They were replaced a few days ago as part of the troubleshooting process. I let the auto parts guy convince me they needed to be gapped at .032" instead of the prescribed .045". The .032 was on his computer screen and I thought maybe platnum plugs needed to be gapped differently for some reason. I'm starting to lose it...
