Yes, its that old chestnut again .Its has had in the last year ,MAF & ECU to cure flat spot and throttle body driver issue .Now come back to us for ABS fault and asked to put it through MOT. Failed emission test co 4.5 @ idle hego voltage stays low 450 mv (rich mixture) as soon as the throttle is of idle sensor starts switching correctly and gas return to normal. injector time @ idle 3.1 ms MAF 12 gsm (seems a little high )? the integrators are 128,114 147 from memory must admit don't know if the the latter two are OK ? Any help great-fully received thanks .
