After reading your post of what you have done you may have some wiring issues. A pulled 02 connector would cause a problem. How good are you with a multimeter? And do you have the wiring manual for your engine / model year?

no never used a multimeter and i don't have the wiring manual. i will ask a shop friend about a pulled o2 connector though. maybe i can get some clarity of that.
