5.7 vortec loping in gear?
Got a stock 98 z71 great truck lots of power however when I'm at a stop light the engine lopes. Rpm fluctuates between 300 and 700 rpm. It only does this in gear. It idles fine . It never dies. I've replaced the plugs and wires, maf, iac, EGR. No check engine light. I'm stumped on what the issue might be and don't want to throw parts at it. Any suggestions on what the issue might be? Your help will be greatly appreciated.
