Re: Service Engine Light - 1997 Chevy Express 4.3 Ltr
After being at the Chevrolet dealership for almost a month (mainly because I didn't need the van as I told them) my problem was eventually solved. Apparently there was a TSB on the 4.3 Ltr engine primarily on pickup trucks and not the Express van, but the dealer figures that the replacement engine came from a pickup. In order to prevent the misfire to cylinder 2 and 5 they had to shim the crank sensor. Problem is now solved. Thanks to all.
