I posted this in the help section too.

My 2006 has 51,000 miles on it. Out of the blue it started running rough! It gave the code P0201 (#1 injector) and P2146 (#1 injector voltage supply)

What the heck is this? Is it covered under warranty or do I have to buy a new injector?

What would cause this? The truck is stock. I change oil and fuel filters regularly. I buy fuel from the same place all the time.

I know the code said #1 injector but this thing would hardly go at all! I hit a very slight incline in my neighborhood and the thing would only pull it in secong gear nearly to the floor.

I shut it off in my drive and when I restarted it, it ran fine after a few seconds.

Any help is greatly appreciated.

 

Its still under warr take it in and have it checked.

 

I will call them today. I just have no faith in my dealership.
