i just bought a 92 chevy z71 5.0l and changed the spark plugs and dist cap and rotor, all the fluids, o2 sensor, and pcv valve.
I noticed when im driving down the street it will be driving fine then all a sudden the engine will idle down all a sudden and start to bogg like and it will do it for a cpl seconds while im still giving it gase then it will drive normal. I noticed also when its warmed up and im stopped at a red like it will almost wanna stall sometimes then idle normal again. anyone have any suggestions on what will make this go away. wondering if it something with the carb not to sure.
