I have a very very low mileage SRT-6. When the car is cold it runs great, once it heats up, the throttle goes virtually dead, no power. We have replace the Engine Control Relay, replaced fuel Filter, confirmed adequate fuel flow, and numerous other diagnostics. Diagnostic check shows no codes, and shows Engine not communicating. Anyone have any ideas? Very frustrated. Any suggestions appreciated. Chris

 

I'm having the same issue and was told it is the intercooler pump. Hopefully the pump comes in this week and I will let you know if that's the cure.

 

Two year later.... snail mail? What happened?

 

Yea. It's the pump. Doesn't give a code most of the time.

 

I went through hell before I figured it.
