Hello, I have an 05 ram 1500 4x4 with the 5.7 hemi. The truck starts right up when cold. After the truck is warm I have to press down on the gas peddle to start. Local repair shops have replaced the cam sensor, crank sensor, New fuel pump, plugs and wires, also have cleaned the throttle body and rechecked the throttle position sensor with a "modus" scanner. I think its something to do with the temp sensor?? Any suggestions?? Thanks.
