hi guys I have a 4.5 installed in my fj40 in the install the person doing the wiring took out all wiring for the knock sensor and the O2 sensor witch makes the motor run lean at all times causing it to run hot.
Instead of doing all the work of rewiring the sensor I would like to know is there is a chip or a programmer to put in the ecm a new tune.
Thanks
