So being new to the world of auto mechanics – I’ve ventured into trying to run what should be a pretty simply diagnostic compression test.
I warmed the car up, started with a dry test. I removed the distributor wires from the spark plugs and from the distributor to the starter.
I started with cylinder #4 (maybe I should have started with #1? – but I didn’t), screwed the compression tester in and turned the key (in writting this post, and re-reading Steve's advice I see I didn't hold the throttle open). I got a very low reading of ± 63. Scratched my head and tried the next one.
Then removed the spark plug from cylinder #3, screwed in the compression tester and got a reading of ± 76.
Then removed the spark plug from cylinder #2, screwed in the compression tester and got a reading of zero. I tried it again, zero. I checked to be sure the device was properly screwed in, and the quick connect was seated. All ok, tried it a third time – again zero.
Decided to try cylinder #1, got a reading of zero. This time called my wife to turn the key, so I could watch the gauge and the gauge was going up put then moving back down to zero.
Do I have a problem with the gauge (which I borrowed from a co-worker) or is it just me?
Thanks for any advice and/or input.
