'H' reg Rover 214 emissions?
My parents ageing Rover 214 (16v with CAT)is in danger of failing it next MOT the emissions have been checked at a Rover dealer, Co2 and HC
,apparently only one can be adjusted which they did the second one could only be got as low as 4.2 and it should have been 3.5 wether that relates to
CO2 or HC I'm not clear but maybe any Rover boffs could shed some light on the reading and give us some suggested remedies.

3.5 is co level....could be temp sensor/O sensor (more likley) or air filter dirty etc

or it could be (known fault with old 214 & 414's) ecu fault developing. Usually a dry joint. First try changing engine temp (to ecu) sender
(cheapest) then try swapping out ecu's or get the existing ecu fault checked at specialist ( usually a 24 hr report service and it can be
accessed through local automotive parts factors, brown brother, partco, etc) .
Hope this helps.

First thing is to do a sanity check start replacing catalysts and lambda sensor an the cost could escalate very quickly , it is not unkown for a a
job the starts out as changing either the cat or lambda sensor to end up changing both and fitting a full exhaust, which is more than even the best 14
year old 214 is worth I know I sold a mint 95 414Sli with 28k miles for £600 last year I wouldn't get even half that now.
First two things to do are known early 90s Rover problems (1) clean out the pipe between the ecu and the inletmanifold/throttle body -- be very
careful disconncting it fom the ECU the connector on the ecu is fragile and get more brittle with age. (2) Also clean the ECU earth point connection
it is an 8mm head bolt located on the bonnet landing panel adjacent to the NS headlamp, remove it clean the connection with emmery and fit additional
spring/star washer as it is not unkown for the bolt to be coil bound.
Lambda sensors get slow with age so it is prime suspect however the one on the 214 can be a swine to change so check it out with a multimeter --- I
think it will be a 4 wire zirconnia type, white wire is signal, black signal earth, two grey are heater +ve and earth. Put a meter on it and you
should see the signal switching very rapidly. If you replace it be sure to get the right sensor for the K series universal ones are not suitable for
the 214.
The temperature sensor is another suspect, the 214 has two, the one that is connected to the ecu has two connector pins.
However I suspect it could be a vacumn leak, check the brake servo connection. Is it single or multi point injection ?
If it is multipoint with the plastic inlet manifold suspect the inlet manifold gasket -- really should be changed every 4 years or so, MG-Rover
issued a TB on this -- modified the gasket and studs. Cars with alloy inlet manifolds aren't affected.
The rotor arm was also a known weak spot on early 90s Rover modified parts were fitted on later models the later rotor arms have a red pint blob on
the shank, if your car dosen't have one fit one.
Plug leads -- Escort CVH plugleads fit.
For cats, and exhaust at the right price this url is useful.

Gendan are a good for Rover lambda sensors http://www.gendan.co.uk/viewcategory.php?category=112
universal lambda sensors are not suitable for the 214.
If it is a single point system I have a Snap-on communicator tool for setting the idle mixture.

One other thing don't try swapping ecu -- Rover MEMS ecu are coded to the flywheel (5 different flywheel codes so the odds of a different ecu
working are 5 to 1) and 5as security unit swappig the ecu means both ecu and 5as security ecu have to be reset on Rover Test Book.

Thanks ...
Thanks for those answers , thats what I like about this forum , we can all draw on each others knowledge/experience,
Thanks for the long exhaustive suggestions 'britishtrident' , I dont know but you seem to be a Leyland/Rover expert.
