I have a 1999 cavalier 2.2 4 cyl with 108,304 miles. I was advised to do a
compression test and did but am not sure if the readings are ok for my
car. The readings are 120 for first three and 135 for last one. Does
anyone know if these are good?

They are fine. Don't worry.

Thanks for the reply. i forgot to mention that my car wont start and I have
no idea what is wrong with it and everyone said to do a compression test on
it first to make sure it wasnt the timing in my car.

Not starting could be anything. Check for codes, check for spark,
check for fuel.

It is a little low but nothing to panic about.
