I just went through this and its gonna get worse.prepair to get the motor rebuilt or just buy a new one.its gonna do this for some more weeks then youll shift into 5th gear at 80 then itll drop to 60 and youll hear a loud pop sound and a rod is gonna break and go through the block.your symptoms are exactly what i just delt with .so get prepaired for a fix or new motor.because its gonna get worse .im telling you right i just delt with this,and got a new motor .your losing compression in the cylinders and somthings bad now and soon if its not broke it Will be.
