Engine Stumbles
When I've got the truck in park or neutral and hold the rpm's at around 1200 the engine stumbles but if I go higher or lower it runs perfect. It's a 350 with a 750cfm quadrajet off a '71 Vette and HEI with a TH350 tranny. Any ideas what is causing this? vacuum leak, carb problems, ignition?
