Cannot get Chevy 1500 p/u 5.7L engine to run smooth without dying out in gear

Asked by Apr 10, 2017 at 02:21 PM about the 1994 Chevrolet C/K 1500 Silverado Extended Cab SB

Question type: Maintenance & Repair

When starts up, it bogs down, will run but bogs, when driven down the street it bucks, doesn’t kick in & run smooth – it doesn’t die out.  Unplugged the temperature sensor & runs better but kicks up to a high RPM & still bucks if drive down the road.  Has no back-fire.  Rebuilt the throttle body, replaced the fuel filter.  Replaced cap rotor wires & runs better but dies out in gear, can run it down the road but have to feather the gas to keep it from dying out.

Check the catalytic converter, it may be plugged up.
