My 03 varies constantly while on cruise control no its not me and no it's not hills and no it's not normal. Thinking it was a vacuume leakI went to replace my vaccine lines as I have on all previous land rovers and found this one to be completely different. Finding only 1 replaceable line very short and nothing else.. Am I missing something and I already adjust throttle cable.

 

There was a TSB on this, the cruise computer needed to be reprogrammed.
Call the dealer with your VIN# to see if it has been done.

 

Ah thanks.. So a Tsb, that means I'll still have to pay for it?

 

That depends on the dealer, some might do it out of the goodness of their heart, others will rape you.

 

also check the rubber vacuum lines around the cruise controler (left fender)for dry wrought, it pretty common because of all the heat trapped under the hood

 

But.. ^ I...,,, uh.... ^

 

Open the old post look at the picture find the actuator under the hood and check all the hoses for cracks or breaks https://landroverforums.com/forum/ge...l-hoses-51467/
