well here's the update on my computer problem. i'd had a CEL for o2 sensors awhile back. had my local dealership pull codes and they told me it was the heater circuits. now i know its rare for pcm's to go bad however, after combing over everything else and not finding any bad grounds etc. i went ahead and ordered a new pcm and installed it. problem solved. no more CEL. idles better. and i am willing to bet my gas milage will improve.(i was running WAY rich).
thanks to those who replied to my previous threads and to everyone else. this website is the reason i was able to narrow the problem down and the reason i was able to do the instalation myself. thanks again!
