I have a 94 chevy 3500 truck the other day when i went to go to work i started it and it was a lot louder then the night before it idles like crap and has no power at all i have to lightly press the gas to get it to move if i press it any farther the motor will cut out until i let off the gas it does run better in the upper rpms. i changed the plugs and wires but still the same any ideas what it could be. Im thinking the o2 sensor but would that cause a real rough idle as soon as i start the truck.
oh i forgot to add i did change the fuel filter that was actually the first thing i did
