I searched for this already and can’t find anything that matches my exact problem. My car idles very rough under 1000 rpm. It gets worse the lower the rpm’s go. The a/c makes it 3x worse also. I had filters replaced, hoses checked, the fuel system cleaned, all mounts replaced. I don’t know what else to do! Please help!
I would do a search for IACV valve cleaning it kinda sounds like your problem this is what controls the idle at operating temp and it compensates for auxiliary items by adjusting the idle as needed.
I would also check your coolant level when i had a bad water pump my car idled like crap.
Thanks I’ll try it out on wednesday when I get it back from the dealership. Until then I’m driving a 2008 TL :bowdown:
