I recently had an issue with my turbo m20. Whenever the boost gauge crosses from vacuum into boost (under load) it shakes the engine/car pretty harshly. If I accelerate smoothly at 30-40% throttle through the entire RPM gauge (in vacuum) no issues, however, the second it crosses atmospheric and goes into boost even slightly, the engine vibrates.
This happened after I replaced my C191 connector (fuel injector connector). I checked my TB, BOV, and all vacuum lines that I removed to get to the harness. Nothing looked ‘off’. I replaced my spark plugs with a fresh pair thinking it was an ignition issue, but nothing changed the symptoms. My car does idle smoother though :)
Any ideas guys. I’m kinda lost with what else it could be. Clutch maybe?
