1965 mustang 289 vibrates!?
Hey guys. 1965 mustang 289 just purchased it.
Vibrates incredibly bad at idle, in park, drive.
Changed my plugs, checked my wires today,
changed my harmonic balancer and nothing has
changed. Motor and tranny mounts seem fine..
is it a stick or auto???????????? flywheel/converter????
How about the cap, rotor, points, condensor, ignition timing etc?
Compression test? I had a Mustang that kept throwing the balance weight on the flex plate, after the third time I yanked the tranny, took it to a shop and they found a ballooned torque converter, after replacing the converter and a new flex plate no more problem. HTH
It’s an automatic. Rotor, cap, condenser is some electronic one that I’ve never seen. Will probably replace it with points.. I haven’t done a compression test yet. Could be a dead cylinder, I think the converter replacement will be out of my wheel house! Thanks for the ideas
