I am getting an engine miss when I turn on my heater, and more noticeably when I turn on my defroster...especially the defroster.
There is no miss untill I turn them on. Does anyone have any ideas?
Any help would be greatly appreciated. Everyone thinks I'm nuts.
Thanks :screwy:

Are you sure its not the A/C compressor causing a vibration? If it where a missfire it would have likely triggered a code and turned on the check engine light. Did this happen?
