Red SLR Posted February 18, 2001 Share Posted February 18, 2001 Any body had this happen on a K series? It happened to me twice yesterday, once at high speed. I had to blip the throttle a few times for it to unstick. The car was accelerating away at about half throttle on its own. Then later at much lower speeds it did the same as I approached a t-junction, the brakes locked and the car carried on. It took a bit of quick pedal work to bilp the throttle unstuck as I was breaking with my right foot at the time. This has worried me a bit, and I am not venturing out today to meet up with the LAD club, esp as the roads are damp. Does any body know the cure? I am going to anglesey in March and I dont want it happening there! Thanks Simon. X777CAT Link to comment Share on other sites More sharing options...
flick Posted February 18, 2001 Share Posted February 18, 2001 Have you fitted a K & N air filter or have you reffited it and Tightened it up to much and deformed the throttle Body causeing the butterfly to stick . The throttle body is only made of plastic on the 1.6 K so this is quite easy to do. Regards Flick Link to comment Share on other sites More sharing options...
Jason Plato Posted February 18, 2001 Share Posted February 18, 2001 Simon , It could only be one of a few things wrong , the butterfly as mentioned above , the cable fraying inside the sleeve , or the throttle mechanism on the plenum . All these are easy to strip and check . Wise move not to venture out before its resolved . Dave Link to comment Share on other sites More sharing options...
Red SLR Posted February 18, 2001 Author Share Posted February 18, 2001 The car is 5 months old so the cable should be ok, but I will check the rest. Simon. X777CAT Link to comment Share on other sites More sharing options...
Jim Ellis Posted February 27, 2001 Share Posted February 27, 2001 Yes, happened many times, also on a brand spanking new K series motor. Many brown trouser events later and much asking around I discovered that it is a common fault with the K series. It is the spindle for the butterfly sticking in its plastic mount. There are no bushes or other forms of 'high tech' bearing and the metal to plastic that is used is not fool proof. The solution is a veyr small squirt of WD40 or similar on the offending butterfly spindle. Since I did this I have had no problems at all. The trouser dry cleaning bill has been reduced dramatically as well. Regards Jim Link to comment Share on other sites More sharing options...

Red SLR Posted February 27, 2001 Author Share Posted February 27, 2001 Thanks I will give it a go. Peter - well I will have to take your word on that.... for now! wink.gif X777CAT Link to comment Share on other sites More sharing options...
Peter Carmichael Posted February 27, 2001 Share Posted February 27, 2001 Because there is no pedal stop, if you are heavy with the right foot you can cause throttle vable damage in a matter of minutes. At 5 months I would make a point of carrying a spare. If it fails it is wear and tear and not a warranty fault. Link to comment Share on other sites More sharing options...
Red SLR Posted February 27, 2001 Author Share Posted February 27, 2001 Peter - if it fails within the 12 months then it is under warrinty surely?! Any way how difficult is it to fit a spear beside the road if it does snap? X777CAT Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted February 27, 2001 Leadership Team Share Posted February 27, 2001 Peter, Based on no throttle stop being fitted, any damage caused by using full throttle (to the linkage etc, not the engine obviously) would be covered by warranty, not due to wear and tear but due to the design of the throttle not being fit for the job, ie. manufacturing fault. Caterham need these kind of claims to drag them into the 21st century. ie. fit a throttle stop! Stu. Link to comment Share on other sites More sharing options...
Red SLR Posted February 27, 2001 Author Share Posted February 27, 2001 So in theory if ou press the loud pedal as hard as you can then the cable will break. This is not very good is it? X777CAT Link to comment Share on other sites More sharing options...
EFA Posted February 27, 2001 Share Posted February 27, 2001 Surely a K Series engined car has to have the throttle pressed hard into the floor most of the time?? Tee hee Arnie Webb The Fat Bloke blush.gif in a Slow Old Vauxhall wink.gif Link to comment Share on other sites More sharing options...
fool on the hill Posted February 27, 2001 Share Posted February 27, 2001 I half remember Derek Moore (classic carriage) telling me that when he builds a seven from kit he adds something at the point where the accelerator cable goes through the front bulkhead/footwell(a rose joint??) so that the cable cannot "catch" at this point. It might be worth giving him a ring about this. Sorry I cannot be more precise - it was some time ago and i didn't have a seven at the time. but it sounds like something we should know more about! James If it ain't broke, maybe it's time I had a look at it... Link to comment Share on other sites More sharing options...
Jason Plato Posted February 27, 2001 Share Posted February 27, 2001 Yes Anie .... the throttle on a k series is stuck to the floor ALL the time , including cornering unlike a Vx where you are too busy sorting out the understeer smile.gif Link to comment Share on other sites More sharing options...
Tazio Posted February 27, 2001 Share Posted February 27, 2001 I suppose you have to have your foot to the floor just to get some performance out of a K, I remember 2CV drivers used to have similar problems..... Alan Link to comment Share on other sites More sharing options...
Mick Day Posted February 27, 2001 Share Posted February 27, 2001 Check the throttle pedal bush hasn't siezed.. This happened to me once on Le-Sept & only a quick flick under the pedal brought my blood pressure back to normal! Mick Link to comment Share on other sites More sharing options...
Graham Perry Posted February 28, 2001 Share Posted February 28, 2001 Mine kept sticking open and even with a new cable we were baffled when it continued, as it has four return springs . We finally found that the finish on the bottom of the throttle pedal was rough and a tiny piece of sharp weld was prominant on the very bottom of the pedal. This wore a very small hole in the the footwell bulkhead when the pedal touched it under full throttle and hence the pedal was sticking to the bulkhead and not returning. At the time I told me mates that I spend so much time with my foot hard on the floor that I wore the pedal out ! Its worth checking this out though.
