Hey guys..
On the '89 SC 5-speed I just bought, I noticed a problem where the car has a very strong vibration or shuddering when accelerating, mostly noticeable at higher speeds like 50+ MPH. The vibration gets worse with more throttle, and at WOT it's enough to make interior pieces rattle.. However, if I let off the gas and coast, it's smooth as butter.
The weird thing (to me at least) is that the car doesn't always do this. But most of the time it does.
Any ideas?
