1996 BMW Z3 Throttle Cable Issue - PART 3

Rubber Grommet
I found the primary culprit when searching for "BMW Z3 Throttle Cable" it is called a "Rubber Grommet for Accelerator Pedal Linkage"(14) it costs $2.00 from this website. Also there is a Clip(11) that looks like it secures the grommet and the linkage to the gas Pedal as you can see in this diagram.  However I cannot find the clip in a store online to replace it I will check with the Dealer to see if it is covered under the previous recall or if they can order the clip for me.

1996 BMW Z3 Recall ID from NHTSA: 97V131000
Auto Recall Date: 08/19/1997
Vehicle Component: VEHICLE SPEED CONTROL
Estimated Vehicles Affected: 410000
1996 BMW Z3 Defect Summary:
THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
Defect Consequence:
THIS COULD CAUSE THE THROTTLE VALVE TO REMAIN PARTIALLY OPEN. IT HIS WERE TO OCCUR, THE CAR MIGHT NOT DECELERATE AS EXPECTED INCREASING THE RISK OF A VEHICLE CRASH.
Remedy:
DEALERS WILL INSTALL A SPRING STEEL CLIP ON THE OUTER TUBE OF EACH CABLE IN THE AREA OF THE ADJUSTING SCREW AND PLASTIC BUSHING. THE CLIP IS DESIGNED TO PREVENT THE OUTER TUBE FROM DISLODGING FROM THE BUSHING.

1996 BMW Z3 Throttle Cable Issue - PART 1

So I drive my car to work, no problems. Shut the car off, work till lunch then I go back out start the car for lunch and have no gas pedal, just a free swinging foot pedal. First thing I do is pop the hood take a look at the throttle housing and cables. I trace them from the throttle body to the firewall and see that all look fine under the hood so I look in the drivers side under the dash and find the black panel covering the area I need to see. I remove two "flathead" plastic screws and remove the panel then I see the gas pedal and it flops back and forth. I look farther up where the Throttle cable connects and sure enough the cable is there and the pedal is disconnected. I try to connect it and there seems to be a missing bushing or something that used to hold the cable in place is missing. I need to get it home so I have to rig it up to work till I can fix it properly without towing it. I DO NOT RECOMMEND DOING THIS EXCEPT IN AN EMERGENCY SITUATION, EVEN THEN I'M NOT RECOMMENDING IT IF YOU DO IT IT'S ON YOU!
I took a small paper clip slid it over the end and through the Gas Pedal connection then I secured it with a rubber band to keep it from falling out. I then Started the car and made sure that giving it gas would accelerate and decelerate with no issue. The deceleration obviously is the most important part here.

However after rigging it up to get it home I will now have to find how to secure it in a more permanent and safe manner.
