Cold weather here and throwing P0300 and the lean bank codes what do you think the odds are I just have a intake gasket vacuum leak?

Ok well I have done much since you guys last posted to try an help me. I am finally feeling healthy (enough) to try and figure this out. I have been driving the truck, when I get the lean codes, I clear them. I don't get the lean codes all the time like 1 in 5 times I drive the truck. I have not set...

Wondering if it might be easier to swap in the 25317628 2001-2007 injectors for the stock 25317669, 25320287 - 1999 injectors Wha'd do you think would that solve my issue? will they even fit? Truck injectors should be the same height and have the same connector, so they should be a direct swap. Sin...

I managed to get the corona virus so that is only making half sense to me I will look up some of the stuff you said to make sure I understand
Thank you again for taking the time to help me understand this stuff.

Wondering if it might be easier to swap in
the 25317628 2001-2007 injectors for
the stock 25317669, 25320287 - 1999 injectors
Wha'd do you think would that solve my issue? will they even fit?

Are you logging fuel trims and O2 mV? What are the values you are seeing? Looks like I need to look up how to log data. I have been looking at the live data (brain logging) and both the B1-1 and B2-1 sensors are showing good wave forms and closed loop is on. One of the post cat (bank 1-2) O2's has ...

Well crap codes came back now its P0174 lean bank 2 (yellow) & P0171 lean bank 1 (red) turned on check engine. But when I had torque re-scan the codes were not present but check engine was still on. I am wondering if they were thrown in open loop? or maybe I need to change or something else. I t...

The stock 1999 engine has 21 lb/hr injectors, the stock 2002 engine has 25 lb/hr injectors. The engine you have is from a 1999, so you have 21 lb/hr injectors. Those will spray less fuel per amount of time than the 2002 injectors that the tune thinks you have. So telling the tune you have smaller i...

Yoda69 Thanks for your help Thank you I just watched a youtube by P locky on how to do that https://youtu.be/GHn4JW41eFk there are changes in B3701 - Injector Pulse Width Voltage Adjustment for the first 4 rows of MAF the voltage is increased (does that mean it sprays more?) Just like you said also ...

Maybe should have posted this to begin with this is the modified bin I was using
