The easiest way to ensure all 6 plugs are firing is to clip a timing light on each wire, as close to the plug as possible (can get false positives by the distributor cap from wires damaged further down). You don't have to shine it on anything in particular -- just ensure it's flashing. The PRV is truly an odd engine because you can lose a plug without the usual tell tale stumble. I lost my entire driver bank on the highway from SEDOC (barbeque'd by a vacuum leak through the passenger intake rail) but the biggest symtom was a precipitous drop in fuel economy, not engine behavior. Power & performance in 5th gear didn't even go down noticeably until I hit some hills. Bill Robertson #5939 >--- In dmcnews@xxxxxxxxxxxxxxx, "K.
