Hello. Just acquired my neighbors 1973 Plymouth Fury Suburban Wagon with a 400ci engine. He was the original owner and the car is just about all original. New parts include: master cylinder, both front wheel calipers, new rear wheel cylinders, front brake pads, spark plugs, I rebuilt the carb, new coil, new rotor and cap, new wires and spark plugs, new fuel pump and fuel filter. The car fires right up, fast idle works as it should, and kicks down after about 5 minutes when you press the gas pedal. I keep hearing a air popping noise in the exhaust and the engine shakes a bit at idle like it may have a slight misfire. Still bleeding the brakes so I haven't taken it on a maiden voyage yet. Any ideas about the popping or the misfire. I will take a video of it and post it up. Thanks.
