How exactly did you perform the compression test?



The intake is already off. I first pulled the plugs. The battery was dying, so I actually had to jump it with the battery in my running truck so it had enough juice to do the test. I'm wondering if jumping it off a battery from a running truck may have given false high readings???

I spun each cylinder over for 5 pumps until the gauge quit going up, then took my reading.
