easy,just remove it & see if it runs ok,it will be noisy but it will still run.
(edit) just noticed you have a 1.4 rover 25,it wouldnt be this cat you need to check by any chance would it [:p]

yeah its for the rover
got misfring and rough idling problems

how did i guess that [:D] also check the pipe that goes from the inlet manifold to the MAP sensor inside the ECU is not gunged up,failing that theres a good chance its the cat.

mate good guess
where is this pipe that ur on about?
really need it sorting as i want to sell it

Hi
Get your lips around it & blow down the MAP sensor pipe to clear it.
Im not sure but didnt Rover use an external MAP sensor on the newer cars?
The MAP sensor might just be bolted on the inner wing or it might still be part of the ECU.
Unplug it from the ECU /MAP sensor & blow towards the inlet manifold, NEVER EVER blow towards the ECU / MAP sensor, You will kill it if you do!
A good hard blow or two will clear it.

cheers
just hoping i can find the right pipe
really getting on my nerves as the fuel economy is getting crap and i look like a right (-expletive removed-) wen the car "kangaroo's"

Just look for the small black pipe coming from the inlet manifold & either going to a small black box bolted onto the body or the cars ECU.
Remember, Blow AWAY from the MAP sensor / ECU!
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
where about is it on the inlet manifold?
i take it the ECU is on the passenger side, behind headlight?
i saw one pipe going thru the wing, but on close inspection, was a connection for something, not a rubber pipe
theres a pipe on the top but tht goes thru the bulkhead
another going to top of rocker cover

Hi
Ive no idea where abouts the pipe is going to be on this Rover 25, Its been nearly 8 years since ive looked under a Rovers bonnet.
The ECU could still be under the bonnet or they could have moved it up behind the dash, I just dont know on the newer cars.
Likewise the MAP sensor could still be part of the ECU or Rover might have made it seperate & bolted it to the bodywork somewhere.
Without seeing under the bonnet I just wouldnt know whereabouts it is, Sorry.
You could ask over on the Car Mechanics forum, The lads on there might be a lot more help with a Rover then I can be

These are the faults stored on ECU
P1185 Upstream Oxygen Sensor Heater - Electrical Fault
P1185 Upstream Oxygen Sensor Heater - Electrical Fault
P0135 Upstream Oxygen Sensor Heater - Electrical Fault
P0130 Upstream Oxygen Sensor Input - Switching Frequency too slow
they say new oxygen sensor , £183 fitted

Hi
£183 for a lambda sensor fitted, Ouch!
The oxygen sensor is in the exhaust downpipe before the cat, Its a screw in fitting & has one electrical plug.
Before fitting a new sensor I would check the earth connection to the exhaust system / lambda sensor is ok.
If the earth is ok then have a look at the sensor, Hopefully its a Bosch unit, Most lambda sensors are, If it is Bosch there will be a 10 digit Bosch ID number on the body of the sensor.
Give that number to any Bosch automotive agent & they can match it up for you.

when i got my MOT done (bout 2 - 3 weeks ago) the tester did say the emmisions were slightly high
heres the details:
__________________________________-
Engine speed measurement was by-passed
Fast Idle Test :
Engine Speed : *Rpm Not Checked
CO: 0.00% vol PASS
HC : 2ppm vol PASS
1.00 PASS i pressume this is lambda
Natural IDle Test:
Engine Speed : *Rpm Not Checked
CO: 0.30% vol PASS
Overall Result : Exhaust emission test PASSED
___________________________
what would cause the CO to be on the boundary on natural idle?
