pj027235 10 Posted July 3, 2015 Any one know what might be causing fault '00587 mixture control adjustment limit 09-10 Adaption Limit Surpassed - Intermittant'. On a warm start the idle lumps over t about 400 - 500 rpm and I think that this is when it occurs. It's a 93 2.0l 16v 9a. Any info appreciated...
