Alas Alas my car is finally running.....only trouble is the damn thing vibrates like a mother#($% and its pissing me off, I already tried to get rid of it by putting bolts in some different places on the flywheel and it got worse. If you rev it up past 4k it seems to go away alittle. Anyone got a clue......

 

What have you done to your car?

 

harmonic balancer on good and tight?

make sure u have the firing order correct

check the timing
