They also replaced the injection pump & mass air flow.
The car idols around 600 and the car shakes you can feel it while waiting for a light, once you give it fuel it evens out, also notice black soot on rear bumper now which I never had before. How much compression should it have and can I test it wet to see if rings are leaking?
