- 1971 Mach 1, Grabber Blue w/Argent stripes. Original 2V 351C Auto, Tilt, rear defog, Black Comfortweave Interior. Under restoration. Original colors, 4V 351C, 4-Speed, Spoilers, Magnums, Ram Air. All Ford parts.
I believe I got some bad gas, need some opinions/advice.
The car was running pretty nice with the Holley 670 Ultra on it. Yes I thought the Fast Idle held on a little too long, but after about 10 minutes it kicks out and had a great idle.around 900 RPM.
Last Saturday I ran some errands and went to get some gas at BP like usual. The card machine was not working on multiple pumps so I got fed up and left. Went to Phillips 66 and filled with their premium, then went home.
Later that evening I took the car to a cruise night. The Fast Idle did not engage and my 7 minute stop and go drive to the cruise night resulted in a lot of fanning the throttle at stops to keep it running. When I drove it home, it was a real challenge and it would not idle at all.
I checked for any signs of a vacuum leak, the added Octane boost to the tank. A couple days later I decided to try her again. 44 miles later, it still won't idle and had some hesitation at some transitions on the highway.
Is there a way to back the metering jets out and clean the idle circuit while the carb is on the car? What else do you suggest?
