I have a 1979 Coupe with an entire 1986 conversion.
Swaped EVERYTHING. It has been fine and perfect for ever now.
Last week it started a strange vibration only when in gear giving
throttle. very noticable cruising in 5th. But absolutely nothing is
vibrating when in 4th gear. It runs perfect there. It doesn't matter the speed
or RPM. It's always there but not there in 4th. Driveshaft looks good and is
tight. engine is smooth, idles great. I can coast and it is fine.
Like I said, only in gear I get the vibration. Oh, and the efi system
was switched out for a carb setup. but that was done a long time ago
along with the motor swap.
Help and suggestions please !!!
