Hey everyone I just bought this car 2 weeks ago and the ETC light will come on randomly. When I stop while in drive it will stall out, however if I place it in park it will still run but very roughly. I took it to the dealer in which i purchased it from and they cannot get a code from it and they cannot identify the problem. Anyone have any idea where to look for the source? They replaced a slight vacuum leak which did not solve the problem. Any ideas are much appreciated!

 

Take the vehicle back to the dealer.

Have them reset the PCM to clear the adaptive memory, and then perform an ETC re-learn and throttle follower test.

The procedure allows the throttle blade to re-position itself. Sometimes it closes a little too much and restricts the airflow.

The dealer can perform this with the scan tool usually while you wait if you schedule it with them ahead of time.
