High rpm miss or cuttin out?
#21
I had a friend who works at GM bring home a Tech2 and some other device and he was able to check the injectors on the car. I know there is a way to do it but I can't tell you how. As far as the other stuff It's difficult going off a freeze frame, watching the live data make sure the O2's are updating at the same rate i.e. one isn't changing very slow compaired to the other. You may want to try switching sides with the O2's to see it the lean condition follows the sensor. This video is kinda dry but it expalins the pcm and fuel trim data well:

God damn my headers are glowing red through the header wrap idling. What can cause that? I hear the rpms jumping form 1k to 1.5k rpm and there is ALOT of air being sucked in to the intake.
What can cause that much air to be sucked into the engine? Today i got the code p0100 and p0336 again WTF help plz

Bank 1 (driver side) is showing lean, it's adding fuel to compensate you want the LTFT's to stay between +10.0/-10.0. For reference "0" = the 14.7:1 AFR the pcm is shooting for while driving. -12.5 isn't too bad but idle should be the easist time for the pcm to control the fuel trims. Have you checked for a bad injector? Also misfires can be misread by the O2's as a lean condition.
I have replaced the fuel pump (walbro 255), Fuel filter is a WIX, FPR is a Delphi, new 02s Denso, New 3 day old tr55 gapped at 50,ignition module is couple of months old, iac is 1 month old.

I have a PLX300 wideband hooked up to Bank 2 and idle afr is 14.7-15.0 and Wot ranges from 11.7 to 13.3. I have noticed the loss of power, like i come to a stop and try to do a burn out and the power isnt there. Then after a lil bit of cooling off it kinda gets there. Ok im fixing to go take it out for a drive around the block to see what codes pop up and what the pids.....
