`I have a 93SC , sometimes the rpm needle goes limp and the check engine light then comes on, when that happens the car will sometimes stall and then I have a hard time starting it again. Eventually the rpm needle will go back to regular idling position and the check engine light goes out.
I had a diagnostic test done and the only code that came up was for the MAF
which was cleaned, could it be the crank sensor? Appreciate any help on this
annoying problem, the other day I was on the QEW and luckily coasted onto the shoulder after a few minutes the car turned over and the rpm tach was normal and no check engine light.
