thats what ive feared all along. you dont think low compression could be caused by carbon build up? I just got my hands on some AC delco engine top cleaner and planned on using it tomorrow hoping it might be a less intrusive fix to the problem
after i run the next 16oz of top engine cleaner i will be checking/replacing the sparkplugs which will be the perfect time to do that test.Low compression in #1
I myself would get the air adapter to put compressed air into the cylinder thru the spark plug hole, moderate 50 psi pressure, and listen for air leak in the throttle body, oil fill cap and exhaust pipe. That is the quickest way to roughly check if valves or piston has issues.
I have yet to retest the compression as the issue has proven to be intermittent I ruled out low compression as the cause for the problem I’m trying to fix. Low compression might be causing an issue of its own but I believe the shaking shuttering to be an electrical issueAbout 3 weeks ago the compression in cyl 1 was bad. What is the current standing of the compression in 1?
That’s where it all started, but after addressing everything that surrounded the cyl 1 misfire, I was able to get the issue to go away temporarily. Other posters said it would be a constant issue if it was due to low compression. Hoping the fretting corrosion fix or something simple does itOk I'm sorry, long thread. I thought the problem was related to a P0301 code. P0301 with low compression is valves or rings. Rings is constant, valves can be intermittent. Good luck!
