misfire in all 8 cylinders

**XxChOpPeRcHiKxX** · 06-05-2009, 08:38 AM

About 18 different mechanics have no idea what's wrong with my car. It's an '02 TransAm, Borla exhaust, longtube header, no cats. A few days after the headers were installed, I hit a major pothole, and from that moment on, it's been running like crap! It misfires in all 8 cylinders, lack of power, and today my legs felt like they were burning cuz of heat coming from under the steering column.

I've replaced the coils, fuel filter, and MAF sensor. The plugs were replaced when the headers were installed. I've checked all the wires and they seem to be good. It will run ok for about a day if put Lukas Fuel Injector cleaner in it. There are no check engine lights, and no codes stored. Every mechanic I've been to has a different opinion about what it could be, but no one know for sure.

By the way, there's only 57,000 miles on it. Any ideas on what could be going on with it? Anyone know a really good mechanic to take it to in the Chicago area? Thanks!

Check header connection to heads on both sides.
Check headers themselves to make sure they are in one piece as well.

That pothole jarred something....
