I have a weird problem with my car at speeds above 55mph. It starts stuttering/missing/hesitating violently. The shaking will stop if I let off the gas, but as soon as I hit the gas again after going over 55 it starts again. Really weird. It doesn't seem to be RPM related either because at high RPM and lower speeds it drives fine.
I have boost leak tested the car up to 30 psi and it tested fine, but that was a few weeks ago. However, it was still hesitating at the time of that test. I was also thinking fuel filter or plugs, which are easy enough to change so they're getting changed tonight.
One thing that should be noted is I have a bad valve stem seal in my #1 cylinder, I didn't think it would do this, but I guess it's possible. Any other ideas? Thanks ahead of time.
*Oh yeah and it's a 6-bolt swap, no balance shafts, and NO porting done on the relief valve (but my oil pressure is incredibly LOW at idle?)
Thanks again,
