What should be the psi for each of the cylinder compression on a 99 Corolla with 148,000 miles with automatic tranny?
I am getting a compression test down in effort to resolve an ongoing misfire issue with cylinder #3 (p0303). I have already changed the spark plugs, spark plug wiring, all 4 fuel injectors and o rings, also replaced and installed new intake manifold gasket, new air filter and also check o2 sensors and map senor. I guess the only thing left is a compression test and a leak down test. Any suggestions or feedback on resolving this issue would be appreciated
