I have an 89 4-door DX 5-speed. Lately, it just hasn’t been quite right. I have a very bad knocking sound coming from the bottom of the motor when it has load on it. (If I’m accelerating hard or shift early)
Since this noise has started, if I drive the car above 70 miles an hour I get a violent shudder after about 15 mins of driving. If I let off the throttle for a second, then keep driving at speed, it takes about another 10 to 15 mins before it will shutter again.
I’m so confused.
To give you an idea of the knocking sound I’m talking about. Image a sound very similar to valve knock but coming from the very bottom of the motor.
