I have had to let my plane set in the hangar for about 6 months due to some family problems. Today I pulled it out and cranked it up with the intention of making a flight. I encountered several problems. 1. the mixture graph on the EM-2 rose to the top and stayed there. The engine would respond to changes in the mixture knob on the EC-2, but not the graph. I suspect that the O2 sensor has failed. Is this max out of the graph a symptom of O2 failure? 2. the oil pressure was fluctuating rapidly between 20 and 70 for quite some time after the start. Could this be just the fact that all the oil had drained during the shut down? I had checked the oil level yesterday and it was down about a half quart, so plenty of oil. It seemed to settle down somewhat after the plane warmed up. OAT was 68 F. 3. the fuel pressure was also fluctuating between the teens and 45. I don't know what the real pressure was but plan to try and check it with a mechanical gage tomorrow. 4. oh and the strobe quit working as well. When I turned the master on to check fuel level, I noticed the strobe didn't work. I flipped the switch a couple of times and the strobe made about 6 or 7 strobes, then quit for good.
