Cm2250 overfueling intermittently

[Rawze]

Any sensor faults?. Maybe a intermittent wiring issue with one of the engine sensors like imap, exhaust pressure, fuel or air temp?. Anyone monitor the sync pulse feedback for the crank and cam position sensors to see if they are in sync?

monitor engine data and catch it when it switches between good and bad?.


- Sometimes it is the not so obvious. For example, I had a truck here yesterday that had low fuel mileage for 2 years, high 4's and low 5's even though the driver was babying the hell out of it. It had been to several places to have it looked at. 5 minutes of it being here, I found the thermostat housing passage for the exhaust back-pressure sensor was 100% blocked up so badly, I had to take a coat hanger and dig it free.
