To all the people that have tried to help me fix the numerous problems I have had with my car over the past year and a half. I finally found out what has been causing it all. I got fed up and took it to the dealership , come to find out the idiot that had the car before me put a PCM out of a 99 into a 2002. I had the PCM flashed for 78 bucks and the car rides like its brand new now. No more transmission problems. No more running rich. All my problems solved!

Over 4 grand in transmissions before I figured it out. I burned up 3 transmissions in a years time. Sucks ass but oh well. Not to mention all the time I had to drive it with it running like crap.
