well here it goes, last night i was driving with about 55mph, went uphill and once i was going downhill, i took my foot of the pedal, the car was still going with about 50 and i noticed my check engine light came on briefly, once i started to slow a bit and it went off. it did happen like this before, going downhill with my foot of the pedal.
can any1 explain why this happened, does it has to do with electrical or air, any advice is appreciated, i mean is it common to happen like that.
