Bad ECM
When the ECM in my Buick died, I had hot spark and lots of gas. Must have been poor timing???
And occasionally, it would run.
It's been several weeks since replacing the ECM and it continues to run well and the gas mileage is back up where it was several months ago.
My key symptom was that the 'Service Enging Light' did NOT come on -- At any time ( even during the bulb check at initial 'key on').
