Okay so when I turn on my defroster my engine will die (at idle). Seems to only happen when its raining or the humidity is up. Nice sunny, dry day it doesn't do it. If the heater is on vent or floor no issues. I'm thinking the cam might be causing this as a vacuum issue. I never had this issue until I did the rebuild. I installed a FMS E303 cam and it now has that nice loap from the cam. Anybody have this problem before? Ain't no big deal but if I come to a light and forget to turn the switch, I'll stall.:banghead And that sucks.
