acceleration? I have a 92 Chevy Silverado 2x4 4.3 1500; it has been cutting out during acceleration in the mid 20 to 30 mph range. then would start to pick up again.it happens in a cold start up and wet. The check engine light pops on then goes out longest has been a min. My fuel looks like it is getting eaten up more quicker than usual. But my gages are a little messed up. The fuel gage moves with the motion of the truck the oil presser goes from 30 at idle to 40 then sometimes when warmed up goes below 30. I already replaced the distributer cap and rotors checked the wires replaced the spark plugs. What else could it be an oxygen sensor maybe?
