110 psi each cyl. However forgot about full throttle position when doing this test per faqs. Want to repeat test with throttle open will this increase my readings.

    Volm,

    Just run the comp test again. It can be done in less time than it takes to post the question. If you let it crank enough to quit climbing, the throttle open will make very little diff, but it is the proper way to do it. So, do it again with the throttle open.

    If it really is 110, that is way low. Check your valve lash to see if it has closed up. Then check the cam timing. Even one tooth off will make a lot if diff to the comp. If healthy, it would be around 170 - 180.

    Charley

    You do not say what you are trying to fix??????
    Maybe you said that 5 or 10 postings ago, how would we know????
    Better to keep a single thread going rather than starting so many new ones.

    What was the result when you swapped the temp sensor? Compression readings may rise with throttle opened.
