I have a 96 audi a4 2.8 v6 and I Have no spark. I have codes p1340 and p1392 pulling up every time I try to start the motor. I have done some research and have tried a few things.

I changed the cam shaft sensor. I changed the crankshaft sensor. and I checked the timing and it is all in good time.


What else could this be? I am completely lost now as I have only had the car 1 month.
