    I run an aem infinity standalone engine controller. I dont need to fool out a CEL. the problem is in where the ground side of the valve ties into all one of the ground carrying junctions. when the OEM grounds are screwed with and an OEM ground path disappears it piggybacks its ground needs off another barely capable ground path and limits current to the coils/injectors if I recall correctly.

    Bought a cheap fog machine online, got it here now will pump some into the system tomorrow and see if its coming out, if its that big surely will come out. I was getting fine till all of a sudden after stepping on the gas few secs later the car dropped revs and recorded both bank 1 and 2 errors (fuel trim) and then started idling around 20 and 22!
