On my 2001 Chevy Tracker, 120,000 miles, one cylinder is reading 50 on the compression test instead of 150. New coil didn't help. Should I get rid of it while it's still running or can this be fixed? It's paid off, but gas mileage is definately going down. I commute 140 miles a day. Thanks

How did that reading compare to other cylinders? With pressure in the cylinder, if you hear out the exhaust, exhaust valve issue. If you hear at the intake, intake valve issue. If you hear at oil fill cap, possible ring issue. I can't tell you to unload it, that's up to you.
