I received the error code P1702. When the accelerator is pressed the truck bucks like it is missing. More so when the A/C is running. Some of the bucking can be eliminated by disengaging the overdrive. Have replaced plugs and wires. Is this something I can fix?

Hi,

I attached the diag for this code. However, this code is not going to cause a hesitation during acceleration.

The main cause of a hesitation is a fuel pump issue or fuel issue in general.

Here is a guide that will help identify potential causes:

Let me know if you find with this information and we can work through it. I am sure if you feel comfortable looking at this stuff that we can figure this out. Thanks
