I have a vibration from 1500-3000 rpm either in neutral or under load. Worse of course under load. Not transmission because it does it with or without the clutch enaged. This is what I have troubleshooted so far:
Eliminated ps pump and ac compressor belts.
Alternator seems fine.
Fan clutch is new and smooth.
Water pump new and smooth.
Timing ok.
Fuel filter ok.
Air fuel mixture ok.
Carbs are synched.
Viewed flywheel through timing hole - no wobble and was cleaned when 5 speed installed
Viewed front balancer - no wobble
Cap and rotor good. Plug wires good.
Clutch/pilot bearing/TO bearing new.
All plugs firing.
I unhooked the exhaust mount from the tranny - no difference.
So this leads me to:
motor mounts? these are a couple years old. I loosened top nuts and not much difference.
coil failing? engine seems to vibrate more on accel than stable rpm.
The vibration is felt more in the car than from the engine compartment and is felt through the pedals and when the clutch pedal is up, through the shift lever.
Any other ideas on what to check?
