Also use a top quality compression tester. The readings from a cheap tester can be misleading. Why are you taking a compression reading? If the car runs and idles fine, I wouldn't worry about it. The best info you can obtain from a compression test is that all cyls are even. If they are all lower than specs, what are you going to do about it?
