GET IT CHECKED OUT BEFORE YOU SPEND ANYMORE MONEY!!!
Just to let you know, I did get CEL's a little while back and both had to do with both O2 sensors. I figured that was the problem and replaced them. My car ran smooth as glass after that, but soon fell right back into the surging crap. I have no CEL's at this time. I miss my custon tune, it runs SOOO much better with it! It will start out great with the custom tune re-installed, run like a charm, perfect, then soon start that surging crap. But even worse than with the crappy stock tune. .....
