Doing a compression test on a 88 FJ1200 returned values of between 80-90psi which seems a little low for my taste
Test was done cold with all the plugs out.
are these values correct? should this test be done with a hot motor?
The readings are usually better on a warm engine.
Did you open the throttle to allow air into the cylinder while doing the test?
Randy - RPM
so i did everything wrong. :empathy2:
Cold motor and diddnt open the butterflys :dash2:
will retest tomorrow and post the results.
