1997 2.0 What PSI should my compression be?
I have a 1997 Probe with the 2.0 (FS-i4 engine).
When I first start the car the idle is normal. But after I drive it for a bit the idle drops way down when I come to a stop; sometimes stalling. (This starts to happen as soon as the car finishes "warming up" I think) I suspect the compression is weak. I don't know what it should be at though. My readings are 90, 120, 90, 110, psi, I know it is supposed to be 9.1/1 compression ratio. I have looked all up and down google search results but can't find the actual compression anywhere. Could O2 sensors be suspect?
