Message	running and warmed up. I have used vacuum gage testing on many cars thru the years. The needle reading and the way it fluctuates can tell alot that a compression test will not. Explained here: [ http://www.atlanticz.ca/zclub/techtips/vacuum/ ] Sometimes a good decarbon can rid the valve seats and stems from pesky carbon power robbing deposits. Do a decarb and redo the compression test and the vacuum test. ZUL8TR in Orlando,FL
