Hello, I have a 2003 Chevy Trailblazer 2wd 4.2L.I start the car and turn the heater on, the rpms go real low a few times then vehicle will stall out. It happens with vehicle in park or drive. If I don't use the heater I have no problem at all, it will not stall.I don't know where to begin to look, please provide me with a few pointers thanks for your help in this matter. Thanks, Tom
