Pondered as I drove to church whether it is really the cats plugging up causing the lack of power and roughness, or if it needs a tune-up...
You know you're a motorhead when...
It's been running rough lately, and talking around, I figured it's the catalytic converters going bad. It does have 194K miles on it, so that made sense. But then I thought, maybe it's the spark plugs and such, 'cause I know sunlit (iirc) had an MSD distributor go bad on him in 13k miles, maybe 40k is enough for the ACDelco part I've got in mine. Guess I'll be popping the hood tomorrow to find out.
