Hi all

I was driving by 1.6L 307 normally... started to accelerate slowly on the high way... approached 150KMH when I heard a BIP and the Yellow check engine light started to flash and a few seconds later stayed lighted permanently...
I started to feel the car shaking pretty hard at some revs...

I pulled the car over, it was shaking pretty hard while idling... I turned it off and on again and it was all ok... the check engine light was gone.

I have a code reader... I now have error pending on P1339.

I am afraid this will happen again.
do you know what that could be ? please assist.

thank you

Jim
