1998 LS400 110k mi.
Starts and runs fine when cold.
Once warm, idles too low, 300-400 RPM, and will die unless either I give it some gas or turn the AC on. No CEL.
Can someone give me some ideas. When I search for my symptoms, I'm just seeing solutions for 1st gen LS400 with the IACV problem. I'm not sure if this one has one or where it is.
Thanks for any input!
