1999 Corolla - Engine Compression PSI

#1
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

What an incredible amount of parts to throw out. That must have been very expensive and time consuming. Very sorry to see this. :(

Why not diagnose and find out what is wrong instead?

Have you Google'd the P0303 trouble code yet?

Should be able to find step by step diagnostic procedures for that trouble code.
