2002 Chevy 8.1L, 30K miles
Two times early last week and once this week the engine has just died for no
reason and restarted without issue.
First time it died I was rolling at 40 MPH in a coast, it died and while
rolling started on it's own again, NO KEY TURN, like popping a clutch.
Second time it died slowing to about 10 MPH under light braking. This time
it took a few seconds to restart using the key, but it did restart and ran
great the remainder of the week.
Third time was yesterday, again sitting stopped at a light. Started right
back up and has not skipped a beat since.
NO Codes in the computer, at least none scannable by a basic scan tool.
Will the MAP sensor act like this?
Is it the likely culprit?
If it is scanned by a dealer's computer, will they definitively be able to
tell how the MAP sensor is working?
Odd thing is this tank of gas also seems to be getting better than usual
mileage out of it.....
I'm thinking about making the $50 gamble and replacing it.
