I've been trying to figure out what is wrong with my grid heaters. They don't seem to be operating as they should. Sometimes they work properly (i.e., cycle when the engine is cold and don't cycle when the engine is warm/hot). Other times they cycle when the engine is hot; for instance, if I shut off the engine and restart right away, they will usually cycle.

I had a thought that for an immediate restart, maybe the air temperature sensor in the intake manifold has not had a chance to warm up enough to tell the PCM not to cycle the heaters. Could one of you 12-valve, cold weather guys try restarting your engine immediately after shutdown and see if the "Wait-to-Start" light stays on and if the grid heaters cycle? I would appreciate it if you would either post or email me with your results.

Thanks, Dave
