Re: Blazer sputtering and backfiring after startup

I agree w/ Rick on the Delco cap and rotor. My '00 van, 4.3L would act the same way and consume a cap and rotor yearly. Had to be Delco. Make sure the rubber seal is good on the dist base to keep the cap sealed and moisture out. Gotta have regular fuel filters changes too. At least annually.
