Check this out guys:
I'm out driving my contour the other day when I get in some traffic the car gets hot and all the sudden it starts chugging real bad. I started scanning it with my palm and it was running very very lean. I have been racking my brain on this and can't figure it out. it only acts up when the engine gets real hot. it doesn't overheat just when the engine gets real hot. Thanks in advance guys.
