Default how to adjust throttle cable

I noticed the other day that I am not getting full throttle. So I examined the throttle cable and it is a little loose. I have the asr so how do I adjust the throttle cable to make it so I have full throttle. :confused:

Do a search under throttle cable in the archived posts. Be aware that this cable also adjusts the pressure in the tranny and if done incorrectly can cause serious damage to the tranny.

On my 96 there is a button you press that is a few inches off the ASR. The cable then can be slid back and forth. I believe other years have a lock that is clicked which allows the cable to move in and out of the mechanism. No idea on the tranny thing though.

'95 Corvettes don't have a TV cable - the A4 tranny is computer controlled.

As for the adjustment procedure, here it is...

Adjustment procedure - Accelerator
1. Unlock throttle body cable adjuster by pulling up locking tab.
2. Disconnect cruise control cable from cruise control servo.
3. Hold throttle body lever at stop/idle position
4. Lock throttle body cable adjuster by pushing tab down.
5. Check that throttle body lever returns fully to the stop/idle position.
6. Adjust cruise control cable.

Adjustment procedure - Cruise Control Servo Linkage
1. With cable installed into servo bracket.
2. Pull servo assembly end of cable toward servo without moving throttle lever.
3. If on of the five holes in the servo assembly tab lines up with the cable pin, push pin through hose and connect pin to tab with retainer.
4. If a tab hole does not line up with the pin, move the cable away from the servo assembly until the next closest tab hole lines up and connect the pin to the tab with the retainer.

*Important*
Do not stretch cable so as to connect a particular tab hole to pin. This may prevent engine from returning to idle speed.

Per the '95 Helms Service Manual...

Good luck! :cheers:
