I have an issue where my throttle gets stuck. A quick tap on the peddle gives back control. I looked at my throttle cable and it is falling apart although still useable. I would like to replace this as a first step in resolving this issue. What is involved with replacing this cable? I have limited space to work on the car at this moment but if it less than 2 or 3 hours I can block out some time at a friends house to work on it.
