I don't know if those two codes are related but for the last 2 weeks I have the P0341 about once or twice a day depending of often I'm taking the car and when lucky I can drive 2 days without having the P0341 code.

Now yesterday while I was decelarating before doing a stop my rpm passed from 3000 to 2000 one shot and at the same time heard a big POW then rpm back to 3000.

I parked the char and later the same day took the car again, the same issue occured once again while decelarating to a stop.

Decide to plug the scanner to see if there was another code than the damn P0341 and found out the P0130.....

What's the damn problen and what should I do. My car is out of the full cover warranty.

Don't know if this can have something related to this alsu but last week I had the Actuetor selenoid cam shat jammed and got it replaced...

Thanks in advance
