So here's my problem, when i start my truck (2000 s10 4x4 blazer) it kind of sounds like its choking. It has a good battery and all the connections are good, when it starts it turns over but bogs down for a second and then runs/ and drives fine.

I just hit 100k miles so i know im due for new plugs and transmission flush with a new filter.

Could the worn plugs and wires be causing this?

-or-

Does it sound like a starter issue?

-or-

Could it be that my spider injector thingys are bad/worn?


Those are just my thoughts, any other ideas?


Edit: ive never had it Not start but sometimes it just sounds awful when it does, and other times it fires right up.
