Hi,
Regards a Freelander 1998, 1.8 K series
It has failed emissions on CO, the reading are high on fast ideal test (0.704 & 0.794) but is ok on Natural Idle test (0.235). All other emission readings are fine.
A couple of months ago I had a basic diagnostic test done and that come up with possible MAP sensor fault. On my early Freelander the MAP sensor is inside the ECU so I have just had the ECU tested at BBA Remain in Kent and they have said no fault found, ECU all ok, also Im getting high fuel consumption at the moment.
A couple of days before the emission test I had replaced the Catalytic Converter & lambda sensor. The emission test result again suggests that the Natural Idle CO reading is OK but as the RPMs were raised the CO levels increased.
At the present time the car starts fine (hot or cold)
Engine runs fine,
And has no fluctuations in revs on tick over.
All spark plugs, Dis cap, filters have been changed.
Any ideas?
Thanks
