On the SX the throttle cable is about twice as long as usual, going as it does all around the engine bay before it gets to the throttle body on the far side. Just this morning it's started sticking, holding the engine at 1500-2000 rpm idle. Any ideas how to lubricate this chappie?

Good idea - there are two different parts o the cable so one is bound to swell up - I have silicone spray for the windows so will try that. Cheers.

Ahh - I think I see the problem now:



As you can see, only one bit of the wire was holding the nipple on! Plus all the fraying was stopping the cable getting back in the 'ole.

After a bit or re-plaiting the cable - luckily it all went back together perfectly - and soldered the nipple back on, almost all was well:



however the cable didn't like the silicone oil I had sprayed down the middle and was sticking really badly, so badly in fact that I though it was frayed in the middle too. So I took it all apart, it was fine, so I put Moly grease all over the inner and put it back together. This time it worked perfectly. It mut be that the silicone oil was too thin.

THe cause of the original end snapping off after a mere 26,000 miles seems to be sloppy engineering - no wonder TVR's got a bit of a bad rep for being unreliable. Firstly the end of the accellerator lever with the cable in wasn't very well aligned with the cable end in the bulkhead, causing it to pull to one side, and secondly the lever was really sharp at the back end - cutting into the cable. So I bent the lever slightly and deburred the hole that it engages in, should last much longer this time. If only they spent 10 minutes in the factory on a little quality.

It was soldered on in the first place 20 years ago and it wasn't the solder that snapped - so I reckon that's safe.

I think the outer is fine - it's silky smooth now.

Bump again! Cable has done 50k miles after the repair with no further problems.
