Emission light staying on

[mgoode180566]

After sorting my gearbox out i started the car and then found that the emission light was on. After checking i realised that i had not reconnected the exhaust sensor which is next round the back of the gearbox.

Is this a case of having the fault cleared ? My guess it registered as the system was open.

Should also add that when first started was misfiring badly. Turnout injector on cyl 3 had failed.

BTW Phase 1 172

as far as im aware now it has read the fault
once you clear the system the fault wont be there because the sensor is back in so should be all good after that

Should self clear after a good drive, sensor may be a bit dirty due to the initial misfire.

this morning after spirited 5 mile drive the light started to flash and car went into limp mode. stopped switched it off. started and still in limp mode. after a mile or so cleared back to a solid light. now running perfectly with light solid.

Wondering if resetting the ECU will help? Disconnect the battery for (iirc) 30 - 40mins and try again after..

On way home last night light starts flashing and car runs on 3 !

Get home check coil pack and no problems.

Check injectors and another has failed ! Thats 2 in a week ! What is going on. Lucky i had a spare from the other day. Now sorted.....

Any ideas why 2 have failed in such a short time ?
