Hi Guys,

So it seams i have been hitting this forum up a lot lately, just trying to iron out any small issues with my 2004 discovery. I have a Lynx diagnostic tool which i plugged into the car the other night. it has a live reading that shows the throttle position. when i have my foot off the throttle it reads 0%, but when i fully depress the throttle pedle it only shows around 66%. Should this be a cause for concern? am i losing precious ponys?

Thanking you it advance

Maybe tighten up your throttle cable so that the butterfly is fully open?You may be surprised by the difference.

Well i feel quite stupid, your prediction was correct. back up to 85% now, which i feel is acceptable.
Thanks :)
