I'm hoping someone can help me to speed up the diagnosis on what's going on with my car. First off I have a 99 GST. 5 speed. 114,000 miles. I had been having some issues with the car surging at WOT. I had just about fixed that then all of a sudden it got worse. I'd have to baby the throttle go go through the power band without it hiccuping. Today when I was about home it felt funny in a different way, I popped it in neutral and floored it. It would get to 5000 rpm and that's it. And when it hit 5000 rpm if hear a slight backfire two mild sounding pops. My plug wires are old along with my ignition coils. Any ideas?
