Hi Duane,

It is a widely propagated myth the LH2.4 ECU "measures injector resistance". The ECU has no circuitry whatever to know the injectors are even electrically present and accounted for, but gets all its info from the lambda sensor. The 113 code, and its "fault in injectors" tag, is derived from the computer's inability to vary the injector duration into a range that results in the expected mixture reported by the oxygen sensor.

Any exhaust leak prior to the sensor will most definitely affect this.

I hate doing this, but I take some comfort in having seen you set the record straight on our Laycock OD mythology.
