So today when I was driving to work, I noticed that when I was flooring it, my truck would smoke a bluish gray smoke from the tail pipe. But only when it would sputter, it doesn't do it any other time. I'm really starting to think I have a fuel injector stuck open?? Is there a way to check and test the fuel injectors?

So today I went to my buddys house and used his scan tool. I'm getting a U1900 code. It's a non mill code. The scan tool I used said, the top 3 reasons for this code are.

#1 Anti Thift Relay
#2 ABS Control Module
#3 PCM

Has anyone ran into this problem before? Does anyone know where to find the Anti Thift Relay or have a diagram for it? And do you think this could be my problem?

I also had cam phaser issues. Ended up replacing the motor. 5K. And now after 32K miles my truck is sputtering as soon as there is a load put on it. Say once it kicks into OD. Sputtering big time. The code says cylinder #3 and O2. Changed the Coil Pack and nothing. I know I have a Remanned motor, but I also know that they put all the original hardware back on the motor. What should I do???

If the O2 sensor(s) fail, your plugs can get fouled. Try turning OD off. If that stops the sputtering, then there's a good chance the plugs just need to be replaced. What were the exact codes that you got?
