Maybe in 2 of the cylinders? I was hoping that it was something simple. I think the last resort would be to open it up and see. I bought the car with the mods that I originally posted. I checked the fuel gauge and it was up towards 60 psi, so I immediately dropped it down to 50 psi (that is what I read from the Helms) if I'm wrong please let me know. There are a couple of other things that I have concerns about:

1) Fuel gauge
2) Tranny whine?

I'll save those for another post, in any case. I'll repost after I change the cap and rotor. Thanks again for all the help.
