The gas or accelerator pedal on this Kia Rio is slack. It has a dead space between touching the pedal and the engine responding. Here is how i fixed this issue.
Step 1: The Source of the Slack.
The accelerator cabke has slack near the throttle body.
Step 2: Why the Slack.
I removed the holding clip and it is clear the cable sleeve holder needs to be moved back. This is causing the slack.
Step 3: Removing the Slack.
Pulling the sleeve back and fitting the retaining clip back in place, the gas pedal is now firm. Driving quality is a little better now.
