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?
