What is the normal cylinder compression in a 2.2L Pontiac Sunfire 2000?

It has 26,000 miles and well maintained.

for a dry compression test it should be around 150 psi. for a wet compres test it should be around 175 psi. those are both test withthe car off and the spark plugs removed. you can do a running compres test and the compres will be much lower usually between 80-100 psi

The normal compression should be between 130 to 150 psi but if all the cylinders are close then you are OK. Most compression gauges are cheap so they may vary.
