Stalls at low idle after warm up
2001 5.3 260kkk miles. After it warms up completely, it will stall at low idle, especially when put into reverse. Had a misfire on 4. Changed the plugs and wires which fixed the issue of it bucking while light acceleration while driving. Removed and cleaned the throttle body, idle air valve, egr valve, maf, new fuel filter. Have owned the truck since 2002, and have replaced the fuel pump twice, alternator once, and recently a rebuild transmission. The truck will flat out scream until it warms up and is idling in gear. Also a new thermostat because I was getting cold.
