Just ran compression test. 245 psi on all cylinders! Car has 81k miles. Thank god. Going to start unplugging coils now. Can I do the same type of test with unplugging injectors? I'm assuming I can.

I honestly don't know why people even bother with compression tests anymore....they hardly tell you anything and will only tell you if there is a MAJOR fault. A leak down test is the way to go. You can have "stellar" compression test results but still have burned valves or even severe oil blow-by causing misfires. I honestly can't even remember the last time I used my compression tester, I always immediately reach for the leak down if I am trying to diagnose any sort of misfire issues.

If I had a leak down test I would. I look at it as why do more work when you can just run a compression test to know if your completely F'd or not F'd. However, if I had leak down capability, I would certainly do so.

Either way. It was 1 bad coil. Purring like heaven now. Going to go enjoy this beautiful day in Jersey. Thank you everyone for your input.

BTW... Furious 7 was a great movie, and the ending was amazing.
