Throwing codes

[batman1988]

I went to autozone a while ago and ran the codes on the car. I got "bank 1 to lean" and "cylinder 3 misfire". I checked my o2 extension wires and my buddie wired up the 2 brown wires wrong. I fixed those and the cyl 3 misfire went away. I am still getting bank 1 to lean. I have had all the injectors flow matched and even changed the plugs. It is still throwing the code. Before my gas milage was really bad, i went 200 mi before i had to fill up. Now i am at 168mi and still have 5/8 a tank left. So today i went to autozone and grabbed there scanner and this is what i got. I dont know if this will help out any or not. All i can say is HOLY TIMING ADVANCE BATMAN!

TPS(%) 0.0-0.4
RPM 780-822
CALC LOAD(%) 2.0
MAF(LB/M) 0.00
MAP("HG) 10.0
COOLANT 180 DEG
IAT 133 DEG
IGN ADV (DEG) 20.5-22.0
ST FTRM1 3.9%
LT FTRM1 -10.9%
FUEL SYST 1 CLSD
FUEL SYST 2 N/A
o2S11(V) 0.030-0.900
ST FTRM11 -1.6
o2 S12(V) 0.450

That is what the scanner showed. So is my 3800 performance PCM causing bank 1 to run to lean?

wouldnt the lean code be a cat code????


and yes timing adv is always high like that when at idle and crusing.

22ish at idle

around 30 crusing

Timing at WOT will varie as to what the tune is set at.

I have a cat-delete and when i ordered the tune from 3800performance they deleted the code off of the car from the second o2 sensor. It ran fine before before for almost a year and a half.

vac leak. At idle do the LFT's go to 16.4?

I have no idea honestly, that is all the scanner would give me for information.

So i found out that i have a major exhaust leak from my rear header to my EGR. Could this be throwing the code?
