A few months back I picked up a 1977 Wagoneer, the previous owner had a long list of work he had done to it and sold it to me with an additional 3 more boxes of parts and said after 14,000 bucks he can't figure out a rough idle issue, nor the guy before he, so as far as I could tell is it was at least a 30 year old problem. I too went all through the thing 2 mechanic friends, craziest thing anybody ever saw AND the engine was rebuilt also. Tachometers, fuel pumps, I mean A LOT was thrown at this vehicle to keep it all together because of the age.
By luck I found Greenway Auto Repair, took it in there praying it didn't need 100's or 1000's in repairs, but seriously within 2 hours they called, all done, $100 bucks, come pick it up. WHAT, REALLY?!?! The issue: An old vacuum plug on the back of the carburetor was missing, adjusted the timing and carb, oh & tightened a hose clamp. Absolutely BLOWN AWAY by these guys! Best place in town, cool, knowledgeable, and I give you guys my highest regards. Thanks you VERY much, and I dig the retro couch in front. I'll definitely be back and tell all my friends
