Answer

Hello, I would need you to do a couple of tests. What is the engine vacuum at idle, 2500 rpms and when power braking, pay attention to needle movement let me know if steady or shaking. Static compression readings (all plugs removed and throttle wide open, fully charged battery). Let me know so we can go from here. Thanks, Nick
