I bought the Viper green 914...have a problem with accelerator, Gas pedal pushes very jerky, not smooth, where to look first? Options

I was the lucky one who bought the Viper green '76 914. Great car. They put in a new accelerator cable before I got it. The pedal pushes real stiff and jerky not smooth at all. Takes most of the fun out of driving. What would you suggest looking at first?

Thanks, Roger

There are three basic parts to the throttle linkage on a 914.

The pedal (and bellcrank), the cable, and the throttle valve.

Pull the pedal forward and pop the ball-and-socket joint loose. Does the pedal move smoothly without being connected to the cable? If not, the pedal should be replaced--there is a hinge inside which can rust and get nasty.

Loosen the bolt that holds the throttle cable onto the throttle valve in the engine bay. Does the throttle valve open and close smoothly? If not, then you've got a problem in the valve.

Then push and pull the cable. Does it move smoothly? If not, it probably needs to be replaced.

Isolate and test. Throwing parts at the car is a good way to spend money without necessarily fixing the actual problem.
