Chevy & GMC Vans

My 2000 safari runs like crap when it rains, doesn't matter if it is stored inside or out. Replaced the coil last month in hopes of a cure, ran pretty OK but has recently started the bad weather behavior again. I'm thinking maybe plug wires? I think I've replaced the coil wire already.

Also, sometimes it seems like when I press the accelerator the engine just ignores it, could that be the throttle position sensor or would that maybe be the fuel pump getting tired?

Most likely you need a full tune-up. Replace the cap, rotor, plugs and wires with quality AC Delco units and go from there. I am betting that will clear up the throttle issue as well.

words of wisdom.

Thanks a million you guys, I'll give it a shot.
