Schrammbo Posted July 16, 2019 Share Posted July 16, 2019 Ok I have a 03 Civic 1.7l vtec. The check engine light code is telling me multiple cylinder missfire. Now I have ran compression test on all cylinders cylinder one had 60 psi and the rest between 170 and 180. Obviously cylinder one is not going to fire but I don't understand the other 3 why they show a missfire. I'm thinking I have a bad compression ring on cylinder one but doesn't explain the rest.
