Having problems with your 1994 Chevrolet C1500 ?
4.3 coolant sensor
\015 Engine on 1994 4.3 Vortec hesitates and falls on face when accelerating. Unplugged Coolant sensor---ran alot better---bought a new one hooked it up and now doing the same thing---hesitating and falling on face.\015
Along with the vacuume leaks I would check the carb. The accelerator pump might be out of adjustment or something else in the carb. Currently I have the same problem with mine and I just adjusted it and for 1 day so far it's ran fine but I have a holley on mine. Carb may be dirty also.
