DBW Throttle position sticking Hi everyone I completed a 5.3l swap on my 98 Suburban using a custom wiring harness to fit from what I can tell a 2011 LMG engine and my stock 4l60E trans. I am having an issue with the throttle getting stuck at high rpms if the accel pedal is depressed in neutral. Its not as bad in drive because theres a load on the engine but doesnt return to idle instantly like it should. If I disconnect the MAF sensor I can depress the accel pedal in neutral and the throttle plate returns like it should but is undrivable. Has anyone come accross this or have any ideas?
