Sluggish acceleration
 

my 95 blazer is very sluggish and the acceleration sucks, more so when i go up hills and around corners, its a 4.3l v6 vortec. does anybody have any thoughts or suggestions on the cause of this? thanks

RE: Sluggish acceleration
 

have u tried plugs, wires, cap, and rotor? Basically a full tune up. That could effect the full power of the vehicle.
Also, try some fuel system cleaner. I recommend techron. Its like 13 bucks a bottle but it cleans the system very well. Injectors, Valves, etc.
Also have you changed the fuel filter? That could cause sluggishness. Changing it works wonders.
