Those compression numbers certainly need to be addressed.
Were you having problems that prompted you to perform the compression test in the first place?
If so, providing us with your vehicle's symptoms will make it much easier for us to accurately diagnose the problem.

Also, did you perform the compression test on a warm engine with the throttle wide open as directed in this link? http://www.geocities.com/dsmgrrrl/FAQs/compression.htm

OK sorry for not being more pecifick but i am having what i think is alot of air in the block ...like alot of air i think that is not suppost to be there...i am sorry it kinda hard to explain but it seams weak for 15 psi and it runs rich alot. i probly do have some boost leaks but not drastic ones.. had this car for about two years and i know what leaks can do..anyways i test the car with it cold with the throttle wide open and five turns on each celinder..so thats about it if that helps

Please use proper grammar, spelling, punctuation and caps in tech posts. Furthermore, don't bump your thread again ever.

Those numbers looks like you were running out of battery. Repeat the test with car fully warmed up, throttle fully open, battery fully charged through out all four cylinders and all four spark plugs removed.

Sorry cant spell, from Arkansas, But the battery was fully charged the only thing i didnt do right was do the test while the engine was hott, and i don't know what you ment by bump been on here for two years now and never had a complaint sorry. I will redue the test while hot and repost. If it makes any diffrence i used a manual tester not eletrical.

Bumping your thread is when you post in your own thread with the sole purpose of bumping your thread to the top of the list for better exposure, see your post #2.

That is no excuse unless English is your second language. Down load and use Firefox instead of IE, Firefox has a built in spell checker for anything you post.

If the test was done with the battery fully charge, I would just go straight to a leakdown test because not only you have low numbers, you also have inconsistent numbers between cylinders.

Ok i will do a leak down test this weekend. But on the firefox issue i hate the program and plus i do understand that this is a professional website but maybe you could be alittle more polite when replying to someones mistakes. But thank you for your help.

I can't think of anyway I could have been more polite but thanks for your feedback and don't forget to cap your "i's" next time.
