After putting up with a sticky throttle for the last year I thought I would try fitting a new cable.
The cable was around the £40 mark and was part no. SBB000280
The symptom was no control over the throttle in the first 1/2" of pedal movement. You would lightly press the throttle, nothing, so you would increase pressure until all of a sudden the throttle would operate. This would give it an on/off kind of feel and make it a pig in traffic.
The only tools I needed for this was a 10mm socket to remove the accelerator pedal, a pair of snips to remove any cable ties and a small screwdriver to help refit the bulkhead grommet.
The job takes about an hour and doesn't need the inspection panel removed.
First you need to open the boot and remove the engine cover/grill to gain access to the throttle body. You also need to raise the rear of the roof and remove the carpet and sound proofing if you have it.
Start by removing the adjustable clip that holds the cable outer at the throttle body. This just simply pulls towards you with a bit of force. This allows enough movement to remove the cable end from the throttle body.
Now push the throttle quadrant open with your left hand and hold it there
and manipulate the cable out of its groove
So that the nipple can be slid out and the cable end pulled free
Remove the cable from the clip that holds it to the engine bracket, close to the expansion tank
and pull the cable free of any obstructions.
It is now ready to pull through the bulkhead
Pull the bulkhead grommet from its hole, I had to cut the grommet as I have used it to feed other cables through that point, but you will only need to pull it out.
Wind the square plastic adjuster clip so that it falls loose onto the cable. This will make it easier to manipulate through the bulkhead holes.
Now pull the cable through the bulkhead hole, manipulating the adjuster as needed.
You now need to push the drivers seat forward, remove the carpet from down the edge of the door, and unclip the cable from the 4 white bulkhead clips. One of which is right at the top
There may also be a cable tie at the top, next to the seatbelt coil, that needs to be undone or cut.
The next 2 clips are down the side of the door slam panel
and the final one is next to the tunnel that runs along the side of the seat.
