SATURN ION CHECK ENGINE LIGHT PROBLEM

2005 Saturn Ion • 150,000 miles

2.2 Liter had sudden drop in power and using gas excessively. The only code is random misfire. We already tested fuel pressure replaced plugs, boots, coil also disconnected the exhaust system without improvement. The compession seems a little low in the 80's. It ran fine then sat overnite and within a few seconds of starting it in the morning the check engine light came on. What else seems likely to cause this?

The compression is in the 80 psi range?Thats really bad it should be around 175psi or better.
