im at a complete loss with my car.


i basically have a the le2 package ( lloyd elliot) with his 224-232 dur with a 592 lift , 36 lb injectors,


but the problem i m having is that the passenger side is running alot leaner, (too lean) then the driver side which is perfect.


i just checked intake leaks, and valve adjustment...

i cant think of anything else that would only affect one side of the engine.

and to my understanding you cannot tune separate sides of the engine with the ecm . solomon is tuning for me,

 

First of all, how do you know that just the passenger side is running lean?

 

thats is what the tuner (solomon) had seen after i sent him all of my data logging, he said the drivers side looked good, and the passenger side was running lean

 

Check your fuel pressure, i had the same problem but on my drivers side, scanned it and it said bank one lean, my car just needing a new fuel pump, runs good now.

 

ok i adjusted the valves yet again and gapped brand new plugs at .030 (as lloyd suggested), and now things are more realistic.


now im fighting a dtc 42 code.......any help to fix this? ICM would be my guess, unless it could be something else.
