Vibration help please.
I have a 90 gsx 5 speed.
At 2500 rpms i have a vibration. It shakes me inside the car just like a bad u-joint, just not as violent. Its pretty isolated around 2500rpms. Doesnt matter if the clutch is in or out, or what gear its in. I Rigged the car so it would stay at 2500rpms and got under it, i grabbed the driveshaft, it was vibrating pretty good, also the transfer case was. I shoved the driveshaft forward toward the transfer case, and it seem to get better, but it could have been in my head. The motor/tranny mounts are tight. I tried to brake torque the motor, there was no excessive movement. Its not the exhaust. The other thing that made me thing, there is 1 pressureplate to flywheel bolt that is sheered off, i no that. But it has been that way for a while and it was fine. Could they be working out? That little inspection cover doesnt allow me to see those bolts
Any ideas would be great, ive got the front of the car in the air right now, ill try whatever you guys think. Thanks.
PS: going down the road, when i give it gas it seems to get better.
