I have a slight wobble in the harmonic balancer only when at idle. I smooths out with just a litte extra rpms. It also kind of hesitates during acceleration. It has new heads, gaskets, distributer, seals,oversized exhaust ect. I bought it that way and it ran perfect for the first 6 months. Then I noticed the wobble and slight miss and I parked it for the winter. Now I want to drive it again but don't know where to go for help. It's a 1991 xr2 turbo. When I first got it I was going to buy your upgraded ecu but now I just want to drive it.
Thanks
