Hi all, newbie (to Lexus) here.
I'm having some sort of high idle problem, about 2000rpms, especially after a cold start. It makes the car a bit unmanageable shifting in and out of gear. When shifting into gear, it seems to shock the drivetrain a lot and if the brake isn't really applied the car will lurch forward. Not to mention, it won't go away until the engine gets good and hot, then it will throttle back to 800rpms. It would almost seem like some cold start protocol going out of whack. Hot starts run 2000rpm for a few moments then it drops to normal idle right away.
The car is a FWD. Also has a very loud but short squeek from engine compartment (belt probably) during starts, done that since it came off the dealer's lot.
Thanks,
Suburbazine
