It seems pretty weird that itd only do it one cylinder if it was the ecm. 40 or 70 pin?So after driving it and watching it a little bit more I'm thinking the ecm is the issue. No matter what it won't fuel number 5 when going slow (mph not rpm) and if I cycle #5 on manually while driving it might run fine for 10 feet or 60 miles but then starts acting goofy. Also the altitude adjustment flickers on off on et a lot. Pressure sensor output stays steady though. It does change but doesn't bounce around. Pretty much the exact same thing happened in june. Had be running fine/normal and then all of a sudden I was struggling to keep it cool and it was slow to cool down.
Am I right in think the ecm had issues and it's randomly over fueling?
