adjust afm lean to compensate for rich a/f mix during limp home mode?
I have a short in the wiring between my tps and ecm. THis is likely due to the jury rigging I did to the pigtail after finding a junkyard tps that wouldnt meet adjustment specs, until I turned it 180 degrees and tested it upside down (vcc and e2 swapped vta and idl flipped)I rewired the plug to compensate for the change and somewhere along the line created a short. The 3vze currently destroys any tps that is plugged into it and The 3vze is TPSless for the time being, until I can fork out another 100 bucks to buy one and splice it into the ecm manually. Im in limp home mode now and will be for some time, Im thinking about adjusting the vafm spring lean to compensate for the default rich mixture that comes along with llimp mode. I am also thinking of placing the appropriate resistor in place of the Intake Air Temp Sensor, equivalent to the warmest reading it can give, to further reduce the amount of fuel being delivered. Could this work, or is my understanding of EFI flawed?
