My car is finally starting up normally now. I didn't change very much, just knock sensor (cuz it'd throw a code when I use any gas except Chevron premium), all 3 O2 sensors (been getting 19-22mpg), and starter (long shot, turned out to be right).

I cleaned the TB too, which I think was causing my car to stall when I shift into reverse (rpms dip real low, and can't recover). My car was stalling at idle probably from O2 sensors, and dirty iacv, which I cleaned out also.

Other things to note: Get a Factory service manual!!! If you're not scared of your ecu harness, there's a buncha easy diagnostic stuff you can do with a multi-meter. Haynes/chiltons don't tell you the whole procedures for diagnosing. The only thing is, gotta have an idea of where to start. That's why I'm thanking the guru's and contributing members who threw out ideas and I went through many, if not all, of the posted suggestions.

I know there are a lot of threads posted here that are not very important or helpful, they are more of "should I get these lights or not" kind of threads, with a few similar threads further down. It is nice to know that there people here that are very helpful when you're in a jam. To those people I also say thank you.
