Intake heater acting funny
 

It's a 92 D250, After start up the indash wait to start light starts quickly flashing, and you can hear the heat coming on and off. I was just going to unhook it as it is not being winter driven, but spring is still pretty cold up here in Ontario. HELP, its driving me crazy(and deadening my battery)
Thanks

mine was doing that to. it will do that if pretty much any of the sensors arent working correctly. in my case the intake air sensor on the manifold had a bad connection. after that it worked good, then started doing it again and i had a relay out. so i replaced that and its worked good ever since. your going to have to get under the hood and start metering things to find out without playing the guessing game
