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. I am afraid to go anywhere now and I need to tow my horses.

Any help is greatly appreciated.

 

Should be covered under your warranty. Possible injector or injector harness which is part of the valve cover gastket.

 

Thanks. I will let you know what the dealership says.

 

That few a miles I doubt an injector died unless you lost the solinoid on top of it. My guess something with the harness or the connector. There is 3 connectors they each control 2 injectors. If you have 2 of them misfiring it can cause some problems and make no power. Make sure nothing came lose on a visual inspection. Also check your oil to make sure you didn't make any. If so have it towed as you have lost an injector for sure. This all should be covered under warranty. make sure you have your reciepts for the fuel filter changes.
