Sean's (& Ed's & Scott's) Astor GTi6

Anyway I left it unplugged, and it's heaps better! The throttle feels sharp and linear rather than lumpy and leggy as before, and crucially the heavy engine braking off throttle is gone! As with the jerk when coming off throttle.

It still has a bit of a numb spot at the top of the throttle, but I'm almost certain that's the fact that the sensor is unplugged as it feels the same as when I ask forgot to plug it in....!

So I think I've cured it! I'll run it without the tps until I can get a new one as it just feels so much better, but tyeah happy days

I think I mentioned earlier on in your thread I had a similar issues and decided to unplug my TPS before driving back from Tesco's and I think it has fixed it as well. I didn't have any noticable flat spots but the main thing was when coming off the throttle the engine braking was very harsh as if I was being clumsy with the throttle but no matter how gently I drove it always felt jolty and not smooth. It's done it for so long I had just assumed it was how these engines were until you mentioned it in here.

I suppose the next thing is to diagnose whether it's the sensor itself or the wiring? Any ideas how to do this? Aren't they like £100 from Pug?
