I have a question... We have a 96 chevy blazer 4.3l v6 4x4, the problem is that when you stop and get ready to take off it spits and sputters but drives fine once you get going. We changed the fuel pump and the O2 sensors but it still does it, ANYONE have any idea what could be wrong????

 

Mine also has a hesitation when it first gets going. Im not sure if these vehicles are very cold blooded.

 

could be a dirty MAF, leaky injectors, dirty air filter, clogged cat or any number of things. I would start with cleaning the MAF first and go from there. GL!

 

Replace plugs, wires, air filter, cap, rotor, fuel filter then see if it's still doing it. Always good to get a tune up done regardless if the engine is running right or not. It rules out a lot of items and starts on a "clean slate" so to speak.

 

Try cleaning the throttle plate, if it is gunked up it will suffocate the air intake and give you poor throttle response.
