Hi, all, I've had increasingly poor idle control when the AC is on over the last year.
With AC off the engine purrs at 800rpm but with it on, and especially at a stop, the engine waxes and wanes between 1100 and 900 like a constant thrumming at about 30-45 times per minute. There is also a very, very slight off idle hesitation that I attribute to the tranny when pulling out from a stop but thought worth mentioning here.
There was only one other post on this forum I could find but it seems unrelated to this specific issue (that guy had injector problems).
Does the LR4 have an idle air controller? This seems to be a culprit in other makes and models. Maybe vacuum leak? Anyone else with this issue?
