i have a 94 blazer s-10 that when you take off it doesn't have the take off especially trying to go up hill it does shift. but kinda slow doing it. 4.3 and 700 r-4 4 wheel drive. any help would be appriecated.

 

When was the last tune up (plugs, wires, cap, & rotor)? Fuel filter? Air Filter? Have you run any injector cleaner? Tried getting fuel from a different station (maybe water in the fuel)? Cleaned your EGR valve?

You have the 4L60E in your truck, not the older 700R4 (4L60).

 

we have change plugs, wires, cap and rotor, air filter is clean, need to change fuel filter and check erg valve, thanks for that tip. my father in law put injecter cleaner in it for me since he had some at his house. and we never go to same gas station twice in a row. with the gas it's usually where ever we are close to when it needs it.
