Just wanted to share this with you guys. I had a bad vibration that started about 3800 RPM. Went thru all the normal problems, damper, motor mounts, water pump(bearings go bad), ect. but still had this bad a$$ vibration. Naturally the problem was the last thing I thought of - it was the FRPP air pump eliminator. Finally I can drive the damn thing.
