Ok, after trying to track down a rich condition ive replaced the O2 sensor with a 4wire and even acquired another chip. Changed the vac block because it was leaking and checked for more vac leaks and didnt find a thing wrong Nothing seems to be helping. I dont know what else to do. I have tlink with some data logged "street WOT blasts" if anyone would be willing to take a look at give me some idea of what to try next. Thanks for any help anyone can offer.
