Starting up issue with 2001 CL600
A fellow of mine asked me to post this question here, as he's not friendly with computers... When he cold starts the car, RPM's go to ~1800 than immediately back to under 1000 and pretty much stay like that no matter what, giving gas has no effect, until he turns off the engine. But, after a restart, everything is fine and normal, no issues. He thought it was something electrical, so he tried to use a charger, when cold starting the car - with charger, there is no issue, either. However, the battery is pretty much brand new.
What could this possibly be? I'd appreciate if somebody could point in the right direction.
Thanks!
