I have an 03 mustang Gt with constant idle issues. In park the car acts like it’s misfiring intermittently. In gear and at a stop the idle will go from 680 RPM’s and gradually lose RPM’s until it reaches the low 475 to 500 RPM’s. While this fall out happens the car vibrates extremely badly and has a hesitation when accelerating. I have no DTC’s except for a P0455 and the car is completely stock except for a K&N CAI and BBK O/R X Pipe. I have replaced the TPS, MAF, Coolant Sensor, all spark plugs and COP’s, alternator, idler pulley, belt tensioner, Torque Converter, Fuel Filter, Fuel Rail Pressure Sensor, Fuel Pump Driver Module, Idle Air Control, EGR, Crank Sensor and Cam Sensor, upstream O2 Sensors, and MIL Eliminators for the rear O2 sensors. Also, sometimes when I go from Drive to Park the car will idle to around 1500 RPM’s and hang. If anyone can help me please do. Attached below is a picture of one of the scanners TID $01 CID $11 data, does anyone know what this means?
