Thread: Accelerator Pedal Very Touchy

  1. #1

    Default Accelerator Pedal Very Touchy

    So everything seems to be working well, but the gas pedal is super touchy off idle. Thoughts? I searched for about 20 minutes, but couldn't get the right answer. Thanks.

    You can add the throttle lever extension to change the throttle linkage/lever geometry. Try the Holley 20-14 Carburetor Throttle Lever Extension.

    You're welcome. A slightly longer throttle lever (extension), slows the "feel" by increasing the travel arc (geometry).

    Hmm, wish I would have known about the Holley extension. I built my own, not quite as pretty, but works well.

    Holley's TBIs used to include a throttle lever extension:

    Actually, I had moved the return spring over from my carb not realizing the Sniper had one with that removed it works great. Easy fix.

    I just got the extension lever #20-14. Anyone have a picture of it installed? Thanks.

    Wanting to contribute to this forum which has been very helpful. I made this little extension just for testing with this issue, but it worked so well I decided to clean it up & keep it. I originally planned on adding a second bolt or pin to the arm connection point, but it turned out that the 1/4" nut/bolt provides plenty of resistance to the extension pivoting on the existing mount, and allows easy adjustment to the angle the arm rests at. Ain't pretty but works great! B.

    Would be nice if they were included it with the Sniper EFI. My truck is a '66 C10 with the pedal out of a '72. I switched it to a cable system and it's very touchy. Cruise at 60 MPH is only about 9% on the TPS & 1% change can be 3 or 4 MPH. Makes steady cruise a little hard. I'm going to machine one. With it being almost $45 with shipping that's just way too high. Jimmy
