Sounds like compression is all good, 155 is spec, but the main thing is that all 4 cylinders are making the same numbers.

ditto . your throttle body is supposed to be wide open and you would probable get at least 155 if you did that. but if they are close to 155 and all even its good.

Yea, plus in the original post you said you only went 3 cranks, go 10 at WOT and I bet comp would be right on the money.

yeah even 140 is still ok if its on all four.
I thought that 160 across all four was what should be on them.
