    April: truck running with lean codes for about a month. One day it drove but seemed that the iacv was acting up and engine stalling at stops. And then a no start without throttle, to force it home. Same the next day to get putt putt into the shop. Apologies for not recording the lean code, but thats what the scan tool said i just dont recall the code. I believe There are two lean codes for our tacomas. So one of the two.
    I installed a rob cee forward facing manifold, with all new vacuum and coolant lines required for the swap.
    Cleaned the throttle body and took the iacv off and cleaned and bench tested with 12v
    Extended four wire harness sensor plugs moving the throttle body and intake box to the opposite side.
    Modified the original intake box to fit and modified tubing for vacuum lines
    Deleted the egr system and installed proper resistor
    Moved the battery to the opposite corner of the engine bay running all new wires and slightly modifying a battery tray to fit.
    When cleared the codes i only have the p0100 code for maf circuit but when i go to start it up it also runs a p1300 code for the ignitor circuit.
    I didnt cut or splice on the ignitor harness and its getting power
    I extended the maf harness and it also is getting power. I have not checked for open or closed circuits and im thinking my kn air filter may have ruined my maf sensor. But thats only a possibility as i took it apart last night and it barely had any dirt or build up on the filiments.
    Im hoping someone could lead me in a good direction for diagnosing the problem. Oem ignitor and maf are 200$ thanks tacoma world.

    Hey guys, maybe a crank position sensor? Or would that throw a different code all together?

    That’s a badass mod!

    u probably know this but posting in case others have same codes
    Only thing that is mentioned in both codes are wiring/poor connections
