Gas Pedal

When I first got my 96 jetta the gas pedal was really low and had little pedal push, 1.5 inches of movement at most. I found out that with this much i only got about half open throttle so I decided to take off the plastic stub beneath the pedal which was nice having a lot more movement and throttle opening. It later regressed to its normal state of only half open and I was back at the beginning. So i found out recently that there is an adjustment in the engine on the throttle cable and I adjusted it and it was perfect. The pedal was up where it belonged and had a nice solid feel, as soon as i so much as tap it i have power and it feels like it should. Now it is regressing again and the cable cannot be adjusted and moved up anymore. It now takes about 1/2 of push before i start getting power. I'm really sick of this and I rarely ever take my car to the dealer cause I prefer to do my own work on my car. Any help on this subject would be much appreciated. I want that nice solid feel back with the power always there

Possibly need a new throttle cable???
Thanks John

First, you very likely need a new cable. When you replace it, be sure to reinstall the black spacer thing under the pedal. It holds down the carpet and prevents wear.

Is the metal clip that locks the cable adjuster in place missing or broken?

Yeah it is missing so I've made my own lil spacer with piano wire but its still actin up a little. I think I'll just buy a new cable. Anyone know how much it is and if you can install it yourself?
