P0171 P0174 Lean Codes 

Thanks brother for the video great information as always.

You rock buddy.. Good work.. Keep it coming.💪💪💪

I see that starter code (P06E9) all the time, it's always accompanied by a failed starter. Late model Ford starters are dropping like flies. Great videos, thanks for taking the time to share.

Great video, thank you for sharing! a little trick I learned the other day with Live Data, if you enter "fuel trim" in the search box, you dont have to search for them in the long list.

Hi brother, I’ve recently had some issues with my LR3 and don’t know what to do now. I passed this vehicle down to my son for school and work and after a couple years just recently we started smelling fuel and it would hesitate to start. He was about to start college so we took it into a european auto shop for repairs. They stated it was a bad fuel pump and the repairs were done. The smell went away but after a couple weeks when I went to drive it for the first time after said repairs, I noticed it still hesitated to start and now it would also completely stall when it comes to a stop. If I slowly coast to a stop it will stay on. Did not want to take it back in so I replaced some part’s hoping that would fix the issue. I did spark plugs, Coil Pack, MAF sensor, air filter and cleaned the throttle body. This did not help and the issue still continued. It did however have missfires on both banks per the scanner I purchased and it got rid of all that. The only codes left are Lean banks 1&2. I took it back in to the shop where they said it was a bad Camshaft position sensor and after they replaced that they said it was a bad Crank case module. They made bith repairs and they said it was my starter or ignition. I told them not to touch those and I picked my vehicle up crom them. Still I was out the cost for those repairs. I then replaced the PCV valve, EGR valve, throttle body and did a injector cleaning treatment. None of these have worked. I am out of ideas and would like some help.

For a Po171 lean code we are looking at battery voltage, transmission, ??

Had a 2008 f250 today multiple issues. Fuse 74 blown goes to maf all o2 sensors intake runner control. Found harness rubbing through on the runner rod. Thought it was fixed looked at fuel rail desired vs actual and actual went down to 25 psi wot

Thanks for sharing Brian. Go cool off Lol 😊

Hi Brian, Could you tell me is possible to flash/update ECU using drewtech cardaq plus3 on Chrysler 200 2016 with a Green C1 connector? Is the tooblox3 software is able to flash/update that ECU?

Well done, you mention that fuel trims go to zero when maf sensor was unplugged. Is that because engine go to open loop

What would be your best guess as to the cause of an intermittent P0174 on my 2008 Silverado V6? Most suspects seem to more of a permanent nature. Loose connector on a sensor maybe?

Hey just seen your video and like the scanner tool your using, If you dont mine me asking whats the model and # for the scan tool TopDon your using thanks indavance, Good Job

only on youtube it's almost always a loose or cracked hose. if only it were this EZ in real life.
