Hello All,
Here is a short but sweet run down of my issue.
Had this DTC pop up for rich bank 1.
Fuel pressure reads 45 psi on regulator before the rails
As i looked into the issue i replaced bank 1 fuel injectors (issue stayed)
Replaced 02 sensor (stayed the same)
Checked for vaccume leaks (None found, i did not pull blower to look at lower manifold.I would think if it was vaccume it would be lean?)
Cleaned maf
cleaned and inspected IAT
(still have fault)
Changed and gapped plugs (all looked good, nothing suspicious.)
When engine idles bank 1 has a LTFT of -18 to -25 (hints why i have the fault code)
Bank 2 upstream seems to be operating just fine
Car has Cams, division x return style fuel system, 2.8 pulley, stock manifolds, not catalytic converters, tune with sct, stock injectors, ummm i cant think of anything else.
I am down to thinking it could be 1 of 2 things either my new over axle pipes that were made are to restricted on that side(the guy used the wrong dye to bend my pipes. I need to get new ones made) , or my FRPS i have noticed with my scan tool does not always read correctly. It is my understanding the FRPS could be used for injector compensation? or it was just left to use soley for tuning.
ANY HELP WOULD BE GREATLY APPRECIATED!
