Hi, I have a 2004 Dodge Ram 5.7 Hemi. For some reason only when I’m at operating temp my truck will stall out at a stop, in park, reverse etc. the RPMS will jump from 200-800 and then die out. I’ve replaced the EGR, new throttle body, MAP sensor, IAT sensor, crank shaft position sensor, I’ve changed all the fluids but it’s still stalling. I’m running out of ideas. Any suggestions?

 

Getting any codes?

Have you reset the computer after changing parts?

 

Well the problem is that my speedometer isn’t fully wired yet so I’m not able to reset my computer nor can I check for any codes due to that. There’s a code for ambient air temp and for the thermostat which I replaced weeks ago. It just won’t reset obviously because the computer isn’t registering that it went over 50 miles

 

Disconnect the battery for a while. That will reset the computer.
