Hey everyone, I finally upgraded from decades of D2’s to a 2011 V8 LR4. Great truck, has 160k on it and just about every repair imaginable done, great service history. That said im running into an issue that has almost everyone (LR techs included) scratching their heads. When I start the truck, turn on the AC and don’t drive, the truck idles great, AC blows cool, all sounds/ runs as it should. But once I start driving then come to a stop the engine goes into an idle fit. RPMs go up and down and I start hearing some clatter from the engine. So, I then quick turn the AC off and the truck returns to normal state of healthy idle. Another way to exasperate this is to start the truck with the AC already ON at start, shift into Drive and boom, idle fit, clatter from engine. No warning light are on the tuck. icarsoft LR V2 tool shows no codes. I should mention I replaced the AC compressor as an effort to resolve the issue, made no difference. All tensors, pulleys V fan are good.
I should also mention that at startup the engine make a brief “clatter” sound for a quick second just before it starts. It’s subtle but present on every start. Just at the moment when you typically hear the starter whirl. Not sure if they are related.
Anyone know wanna take a crack at this? Buy ya a beer…..
