As you can see there has been alot of stuff thrown at this car...



It Misfires all the time and can only be felt at idle. I have done the engine mounts. After all the work I have done, it is 10x better and its a small misfire....but its still there as I can feel it.
I can also hear the engine surging rhythmically.

At this point....where should I go? Should I look into fuel delivery/computer or what?
Injectors as I have only had one replaced in my lifetime with the car?

At least I can safely say the head is absolutely 100% Perfect. Top end is set for at least another 100k miles.
