Good Morning,

I have posted previously--thanks to those who have helped!
I have two fault codes.
First is pin 8 code 13. This is well described in past posts.
I also have pin 14 code 11 (closed throttle recognition signal to engine control module) Could this cause idle surges when transmission is in drive and car is stopped at stop light? Surges seem to lessen if transmission is placed in park. I searched for previous posts on this problem and found only 1, but no mention was made of idle surges.

Thanks,

J. M. van Swaay
