I experienced idle speed very high during my driving, so the rpm drives very high and car is disengage from speed and I have to pull over, turn off the engine, wait and turn on the engine and everything is OK. Happen very rarely and I don't know what cause this situation. When I go to service, they hook up to the computer and computer shows no error. Thanks for any input and help.

 

6K ago I did 100K service and according to them everything was OK, but I will check again - thx so much for advice, I will definitely check the eobd2.com. for some diagnostic tool to fix my problem.

 

You have to check codes from transmission module, not only OBDII engine codes and it should show them the last problem stored in the memory.
