Idling Problem - help
recently showed up ... noticed it a little yesterday, worse today.
normally my truck idles at / around 750 rpm ... today when i was on the way home from work, every red light ... after 15 sec of not moving, the rpm would drop below 500. thought it was going to stall. then after a few, it would go back up. then drop right back again.
and man this is scaring me. Any suggestions or ideas? Is it something I can fix in my driveway? or should I bring it to the mechanic at my work tomorrow?
