Hey all,
I've been having a problem with an old '82 Ford F150 I picked up. When I start the truck I either get a real rough idle but no stalls or a real high idle. I just bought the truck so I'm trying to make sense of the ups and downs, but would this be indicitive of a vacuum leak or a carb problem? I tried cleaning out the carb with some of the Gunk cleaner, but it only seemed to drop the idle speed when I sprayed it in and it didn't help the overall performance. I can't see any kind of loose/severed/broken hoses, so I'm at a loss. Hopefully AF can help me pull out another miracle with this old beauty.
