The most life threatening niggle...
Discussion
When it comes to TVR ownership we all have our little niggles, but the other day I experienced somthing that I thought impossible.
The other dayI stopped at a traffic light, and the water temp was a little high (114) and was advised when in traffic and running a little hot, rev the engine upto 3K or so a few times to encourage water circulation... So, as advised, up to 3K went the needle, and then suddenly, upto 4K and it just stayed there, confused for a moment, and making a heck of a racket, I realised the accelerator was stuck. I quickly tucked my toe behind the pedal and pulled it back. I thought to my self if that happens while taking a corner, I am going to be in BIG trouble...
So today whilst turning into my underground car park slowly, the accelerator somehow gets stuck, all the lights came up!! I had the clutch in, and reached down with my hand and pulled to pedal back, parked very carfully, and thanked everything holy that I wasn't on the road...
I can't understand why that would happen, if this has happened to anyone before please let me know what the situation was.
I am a little worried to drive it upto the TVR Centre and might ask for a lorrie, please advise.
Many thanks,
Niro

I'd be more worried about why your temp is hitting 114. Either you have a faulty temp sender or the fans are not coming on. Even in the ultra hottest 35 degree heat in major traffic jams it should go much above 102-103. Are the fans coming on and cutting out again? If so its probabl a dodgy reading.
I've heard of throttle cables snapping - seems to be reported more on hear on Sagarises, not sure why as I'd have thought that was the same as T350/Tamoras. Not heard of one getting stuck, but check the mechanism is moving freely on top of the engine - halfway along the inlet tracts.
All you need to do it dip the clutch to prevent an accident. Just don't be tanking along and be ready to do so.
Hope its an easy fix (sounds like it is).

That is one hell of a "niggle" mate.
I haven't had anything like it, so I cannot help you diagnose it, sorry. But it sounds pretty scary - I would get her sorted properly, and I would probably get her there on a lorry rather than drive her.
Also, you should not be seeing 114 even in traffic; the fans are supposed to come on at 92 and 96 and they should keep the temp below 100 degrees. Over 100 the water is trying to boil; it cannot as the system is pressurized but the temperature and pressure will be very hard on the engine, and eventually something will go pop.
Good luck with her.

Had a similar problem in the tuscan, check the cable isn't getting stuck at the pedal end, this can happen if its not correctly adusted. also check all the springs in the thottle butterflies are present and working correctly.
by your description i assume its the former rather then latter

Had a similar throttles stuck no brakes moment as an apprentice once.
Shit myself !
Single track bumpy road throttle stuck braked and nothing.
A false metal hip insert from a Crematorium had slid up under the brake pedal pivot point due to the bumpy road, as the lads had put the warm item on the van floor as a joke.
Talk about revenge of the dead. Finally stopped and tried to remove said item and I swear it burnt my hand. SCARY

Hi all
My T350 used to get 105ish but i read that the speed six is very very sensitive to water levels. If ya level goes below reccomended in handbook then it can get hot. I found my exp tank empty and bone dry, popped some water in her and she is mint now. Never goes above 96 at all and hovers around 90 ish in traffic.
Best check ya levels, might fix it. But cant help with throttle, sounds like a pro is needed to fix that one.
Hope all is cool mate (excuse the punn, not intended)

Thank you all for your comments, and advice...
Took the car in yesterday, checked the throttle at the peddle end, and the butterflies and springs... couldn't find an obstruction as such, but just greased the mechanism to keep the grit off... Luckily didn't find any metal hips
Regarding the 'kettle', had a few little leaks in the system, so was losing water and my temp gauge was off by about 10 degrees.
The crazy thing is that my expansion tank is completely inaccessible unless I take the whole bonnet off (not just the service bonnet). I can't even check the water level!!
All sorted for the moment...

Please can I have some mail too! My accelerator just stuck on the way home. I pulled over straight away and switched off for a few seconds. Restarted, but still revving high so switched off again, this time for a bit longer. Whilst waiting, I reached down and wiggled the pedal a bit to see if anything was amiss, but all felt OK. Started again after a minute and all back to normal! I'm going to pop outside soon and start it up again (before it gets cold and doesn't want to be revved hard!). YP
Well, I popped out to the car to give it a bit of a rev, and it seemed fine. I couldn't feel any abnormal resistance in the cable, and inspected the pedal closely and couldn't see an obstruction. I'm wondering if it might have been the edge of the carpet sneaking under the pedal. When it happened this afternoon, I instinctively pulled the carpet away from the pedal box when I stopped, so I can't be sure if that was the problem. Anyway, I carry a spare cable and will stop immediately if it happens tomorrow, but will get the cable replaced anyway.
I had a sinlge event about 3 years ago in the Tamora - stopped at traffic lights, revs went up to about 2.5k (foot off the loud pedal) and stayed there. Pushed the pedal once, everything then OK (ie revs dropped to normal idle). Never happened since. Your experience is clearly more significant, but sorry I can't help more.

I have found before that the bar at the bottom of the picture above, that the linkages are all pivoted on , can bend . The arm that pushes the brake master ( inside the gaitor ) pushes from the middle of an 8mm mild steel bar where it is unsupported . If you push hard on the brake pedal the bar will bend and cause the throttle linkage to stick . Changing the bar is not easy but when I do it I put in additional bracket to add support to this area , David
One of my quick check areas every 6mths on TVR's has been to smear a little Copaslip on this and the bonnet release cable, when both are at full extension. As many will know, Copaslip stays in place better than normal greases as it's designed to withstand high brake temps.
Never had one go since I started doing this, but did several times before
