THE SERVICE ENGINE LIGHT AND TRAC OFF LIGHT GO ON, AND IT STARTS RUNNING ROUGH. THE SCANNER CODE SAYS ITS THE IDLE SENSOR, BUT I HAD THE DEALERSHIP REPLACE IT. WHEN I RESET THE SERVICE ENGINE LIGHT TO OFF IT RUNS FINE. THEY TOLD ME I MIGHT NEED TO CLEAN THE THROTTLE BODY INTAKE. WHAT SHOULD I TRY.

Common causes besides IAC are

A vacuum leak
Leaking air intake after the throttle body
EGR valve leaking vacuum
A faulty positive crankcase ventilation (PCV) valve
Damaged/failed/dirty throttle body
Failed EVAP system

It sounds like vacuum leak on the drivers side, but the hose runs through a bundle of wires, covered with heat insulated tubing
