joecool911 Posted September 15, 2013 Share Posted September 15, 2013 I'm thinking my heater block for intake is not working. Do you get any codes if this is the case. It usually came on in the morning in the past for maybe a few seconds in weather in the low 50's. It starts, but kinda sputters a little. Hoping to hear a little about what you think. Before it gets too cold.i found the article on grid heaters. Sounds like the temps lately have been on the bubble for grid heaters to come on. I'll wait for cooler weather for final diagnosis. But it's on my radar screen. Link to comment Share on other sites More sharing options...
Administrator Mopar1973Man Posted September 15, 2013 Administrator Share Posted September 15, 2013 IAT sensor has to drop below 60-65*F for grid heaters to start. You might want to verify you IAT temps.P0380 and P0382 are both error codes for grid heaters. Link to comment Share on other sites More sharing options...
