No Heat At Idle - Temp Rises. Slight Throttle, OK.
More problems with my POS lemon 2005 GC with the 3.7L. Now, at idle if I sit long enough, the temp slowly starts to rise towards Hot. Also, there is little, if any heat coming from the heater when at idle. If I give it just a little bit of gas and put the revs just off idle, the temp starts to come down and there is heat.
I've replaced the thermostat and it still does it. What else could it be? Water pump? Could it be worn enough that it doesn't move water at idle but just off idle is enough to get coolant flowing?

P.S. I love Jeeps, but I freaking HATE, HATE, HATE, HATE this $#%$%ing lemon.

check for air in the system (burp it). Then check the water pump. My chevy trk. does this when the coolant gets low. If coolant is ok, the impeller on the wp may be worn enough that it's not pushing the coolant through the system.
