New owner, please help
I am a proud new owner of a 1999 Superformance and am looking forward to learning allot from you all.
Need help with a gas pedal problem. It has about 3/4" play when depressed before it engages the throttle. It is sticking down just at throttle engagement. It does not appear to be sticking on the shaft to the carb. From time to time I have to lift the throttle from the underside to bring it back up. Reminds me of dead peddle on a bad clutch. I checked the spring and it seems okay but could it be as simple as replacing the spring or could it be something else? Thank You |

i dont have a SPF.....but if you have to pull the pedal up with your foot to shut down the throttle then i would start by replaceing the spring......if it is a cable then find a can of cable lube ( motorcycle shops sell it) and lube the heck out of the cable and look for any spots where it may be beginning to frey.....if its mechanical linkage then check for where it may be binding up....broken motor mounts have been known to let the motor rock enough to make the linkage bind while going around corners...
hope this helps...... welcome to CC... post some pics.. |
Once you solve your problem, make sure you also have dual return springs in place.

I have the same problem with mine if I try to remove the throttle return spring that is mounted on the inner fender.
Take a look and see if you have a spring there or not. If not, let me know and I will try to get a picture of what I'm talking about. |

The gas pedal hinges on a bell crank throught the pedal box. The gas pedal attaches to the bell crank with a nut on your early car (with a small bolt on later cars). Over time the attaching point of the gas pedal to the bellcrank can become loose and tightening the nut more can cause the pedal to lock up the bell crank in the pedal box bushing. To check this, back off the nut a little and see if the movement frees up. If it does, you either need to repair the current pedal and bell crank, buy new, or this is my solution. Modified Gas Pedal Lever You can fab this yourself or I have extras I will sell you for $50. including shipping Craig |
Here are a couple pictures of the throttle return spring I was referring to.

That is not a factory install. From the factory the car is delivered with a spring that pulls the pedal back in the foot well. The only other springs are what are attached to the carburetor. I also see your linkage has seen some excessive bind because of the way the bell crank lever is bent/twisted. When adjusted properly, you shold be at WOT at the same time as the gas pedal hits the floor. If the carburetor gets to WOT before the pedal gets to the floor, you will bend linkage. Craig |

I actually have three (one on the pedal, one on the linkage, and one on the carb), but that is probably overkill. |

I do not recognize your photo. This is the where the gas pedal connects to the bell crank inside the footwell? Can you take another photo of the other end in the engine vompartment? Craig1265 |

I had a Superformance here where the pedal had stripped it's attachment to the shaft. The pedal couldn't be removed with the motor in place so I welded it to the shaft for now. It sounds like it is binding where the nut holds the assembly together. Check that first. Make sure you're throttle isn't running out of travel and bottoming out as that messes with the linkage and as pointed out have at least two return springs, one on the carb linkage and one on the pedal. Check out SCOF as it's a wealth of knowledge on these cars.

Hey Phoenix,
Jeff here or one of the AZ gang. I see there is a new owner in the state and wanted to say welcome and invite ya to one of our gatherings. Check your PM list for some info. |
OK
Their must have been another configuration on very early cars or your has been modified. Your gas pedal appears to be welded to the shaft in the foot box and the lever in the engine compartment held onto the shaft with a set screw. Yet one more configurtation Craig |
