I have a 1997 Chevy S-10 Blazer, 4.3L Vortec V-6, push-button 4WD....I'm having a problem with sputtering. If I accelerate lightly, the vehicle shifts fine, but if I give it gas to make it go, it sputters like its going to stall and my RPMs go all over the place, also causing my check engine light to come on....for the past week its been in the shop where it recieved a full tune-up: plugs, wires, cap, rotor, crank sensor, catalytic converter....I'm tired of paying money only to still have the same probem...Has anyone heard of this, and maybe could give me some proper advice as to what it may be?
