Wanted to thank everyone for helping turns out both cats are better than 90% plugged and the o2 sensors were pretty nasty looking. I replaced the 02 sensors but the cats are too far gone. I'm still...

sorry for the confusion about the o2 sensors but I "cleaned" them.

So pretty good chance I ruined them.

here is a short log.
misfires in cylinders 1,3,5,7

sorry it took so long to figure out how to set up the scanner to read it.

I really hope this helps solve the problem.

Thanks...

Only permanent codes, seems to run fine till it hits operating temp. Low on power but doesn't backfire till I hit operating temperature.

Added new map sensor. Also tried a vacuum test couldn't find any leaks. I have no clue what's going on.

Just found out the fans will turn on if I unplug the maf.
The truck idles smooth but fans will not turn on but once I unplug the maf the fans kick on and it runs rough. But it doesn't die.

um also I cant get my cooling to kick on even trying to turn them on in hptuners.

now I also have these besides the misfire and lack of power.

Dealership checked the evap canister. Wait what... is the purge solenoid supposed to wiggle? Hmm think I'm going to replace that. As far as the cats they have a slight brownish orange tint to them,...

New Air filter, have two different throttle bodies, the stock one and a lingenfelter tb. Swapped tb no difference

I will try to get a log posted soon.

I did the hpfp and did change the oil. I noticed no other issues. I'm already 4 grand deep and I'm running out of stuff to replace that might be causing the problem. I have no clue what's going on.

Ok update... new hpfp installed same loss of power, bad mpg, backfiring. No check engine light but when I put a scanner on it it says p0101 maf low.. swapped it with brand new maf same problem. At...

Just noticed about a half inch of fuel in the oil... wasn't like that before I took it to the dealership

Just got it back from the dealership. They said all pressures are good and it's not the pumps. Still straight gas smell and the inside of the intake is wet with fuel. Hoping that it's working fuel...

Had a solid tune in since April 2020. Just recently had a massive loss of power and multiple misfire and lean codes.
Replaced coils, wires, plugs, maf sensor.
Then found fuel in the vacuum lines....

Thank you all for looking at my mess. I have adjusted everything mentioned. I will have Saturday to log if it is still acting strange. I will remove the canned tune and start from scratch. I promise...

is this due to the 02 error? it runs lean since the install of the ported throttle body I havent straightened that out yet since I'm still learning.
would it be better to reinstall the stock tune...

All i changed was the info in the bluecat program in the transmission. Before that i changed the idle settings for the ported throttle body and added 5% to the driver demand table. All my previous...

Hello everyone, I'm still very new at this but I just installed a new trans tune. I noticed right away a change in my fueling. starting at about 2900 and going up from there. I didnt see that on the...
