Poor acceleration?

This sounds like you have a weak fuel pump or a clogged exhaust system. Let's start by running the codes to see what comes up,

Also, it could be the MAF sensor needs to be replaced.

Here is a guide below that can help as well:

Here is how to change the MAF sensor out in case you need it. Check out the images (below). Please let us know what happens.

I have the following codes:
P0332-Knock Sensor 2 Low Voltage
P0113-Intake Air Temperature (Iat) Sensor Circuit High Voltage
P2228-Barometric Pressure (Baro) Sensor Circuit Low Voltage

Here is what is said about these codes:

P0332 - Knock Sensor 2 Low Voltage:

P0113 - Intake Air Temperature (IAT) Sensor Circuit High Voltage:

P2228 - Barometric Pressure (BARO) Sensor Circuit Low Voltage:

So, we need to check the catalytic converter because if it is partially clogged it can cause these codes.

I got the engine to normal temperature. Turned off truck and took the following readings. I have attached a photo.

The truck needs to be running when taking the readings but from what I can see the cats might be clogged up. Please resend the readings.

I retook the temperature reading while the engine was hot at normal temperature.

The first cat looks okay, but the rear cat looks like it might be clogged. Also, I noticed a big difference in the input temperature on the driver's side, is the engine running smoothly?

i'm still have a delay or drag when accelerating. I'm working with another member on a knock sensor code. And I forgot to mention that I cleaned the MAF Sensor, and that code went away. I only just have the P0332 code.

The P0332 code is a generic OBD-II diagnostic trouble code that indicates a problem with the knock sensor circuit on a vehicle.

Some common causes of the P0332 code include:

Faulty knock sensor:

I would do a fuel pressure test because lack of fuel can make it ping and cause the code. You can rent a fuel pressure gauge at the local auto parts store for cheap or free here is a guide to help.

The fuel pressure should be about 60 PSI

Check out the images (below). Please let us know what happens.

i have 52 PSI of fuel pressure.

I connected the gauge and turned the ignition on. The pressure gradually went to 54 PSI and slowly dropped to 52 PSI. Started the engine and the pressure jumped to 60psi. I applied the emergency brake and put the truck in reverse and idled the engine and the pressure held at 60 PSI.

That is a good sign, I think the pump is okay, did you try a new MAF sensor they can cause low power and not give a code.

i will install one and get back.

Sounds good, have a nice weekend.

I installed a new MAF Sensor and the code came back.

What code comes back? If you are getting the BARO sensor code you could have clogged cats, you might want to undo the head pipes and drive it to see if the power returns, if so, I would replace the head pipe and catalytic converters.

Here is a video to show you how:

Please let us know how it goes.

The P0332 knock sensor code.

Can you upload a short video of the engine running so I can see what's going on? Can you hear the engine making noise while running? I have seen the knock sensor wire lead go bad and cause the knock sensor code.
