I have a 2005 Chevy cobalt about 115,000 miles .we are getting a check engine light and the p030 code .I’m doing a compression check on the motor before replacing the coil/ignition module and plugs .on cylinder 1 I’m getting a reading of 120 ..on all other cylinders I’m getting a reading of 150..is this too low or still in spec??appreciate any advice !!
