Well thanks for the answers, I pulled the filter back off, poured it full of sea foam, poured the remainder in my tank. Didnt help at the time, got ahold of my mechanic he said try to limp it over to him. It started running much better after a couple miles we put his codereader on it and it said fuel pump relay, which I just replaced, it also said running lean which makes since as that is what it acts like, he is going to check the fuel pressure before and after the filter and we will go from there.

 

Update, he called and said O2 sensor bad, ordered it and replaced it, I went and picked the blazer up runs the same or worse, i put premium gas in it and drove it back to him this morning we hooked it up and said O2 sensor bad again it is only working intermittantly, he ordered another sensor to put on tomorrow????

 

I am wondering, wire from sensor to computer or computer itself?
