94 blazer stalling, hesitating, backfiring, and cutting off
I have a 94 blazer and I was driving and that tach started jumping and the truck started bucking and hesitating all of a sudden, I couldn't go fast at all. I changed the plugs cleaned the injectors, cleaned the filter and changed the ignition coil, the wires and distributor cap and rotor button are two months old, it seem like when I start it up and go around the block I have full power, but after about 20 seconds of driving it start jumping and bucking and even backfired. Someone please help me out
