So I pulled out the injectors and tested them and cleaned them. They were good. With a rubber tip blow nozzle and a plug I tested the HPFP, and wouldn't you know it gas and bubbles coming out of the bottom piston seal. Getting one ordered with new O-ring kit for injectors and intake gaskets. I will post once work is done. Fingers crossed I will be good.

The MAF tested good. So I decided to just yank off the intake and ordered a injector tester. So when it gets here I will test them and if they are good I am going to put in a new High pressure fuel pump and cross my fingers. I might even just replace the pump and injectors.

The O2B1S1 was 0.110v. I must have skipped past it last night. The high pressure fuel rail at idle is 484.4psi. I have had her since birth and the station we use don't have E85 so it should be regular unleaded.

Thank you for all this info. There were no codes for the MAF but the other scanner showed a voltage error. I will run though all these tips tomorrow and see if I can find anything out.

Hello, I am new here but out of all the reading I have done this place seemed like my best bet at a last hope. I have been having an issue with my truck the least few week. When it is at idle after being warmed up and/or on a hot day my traction light comes on for a moment and then goes off. After that it seems to downshift early and takes off a bit fast. If I turn off the engine and start it back up it is fine. It has codes stored but the light don't come on a lot and when it does they are gone in a few hours. I have been reading and watching everything I can find and I am now at the point where replacing stuff is going to get expensive. I had a friend hook it up to his scanner and it showed the coolant temp and MAF sensor with faults on top of the P0172/175. So, I have replaced the plugs, wires, MAF, Coolant temp sensor, PCV Valve and have put seafoam in the gas tank. I have also cleaned the MAP/BARO Sensor. I ended up buying a cheap scanner so I could see some live data. I am at the point where I don't know if it is injectors, High pressure fuel pump, fuel pump, or something else I am missing. I will post the numbers I seen while at idle. I would post the pictures but they have too many MB. On another note there is a hint of gas smell on the oil dipstick. I would say I have better then average ability to work on vehicles myself, I have never been to a shop for anything but the tires and a oil change cause its not worth the time to do it myself. I really appreciate any help that I may be able to get. Thank you for even taking the time to look at the post.
