my 2.0 is running on RS1800 loom and ECU. l've taken it to tuners and got the emissions down as low as it would go but its still running rich. would putting the original mondeo air filter on lower it futher? l need to get it down so it will pass MOT.

any ideas would be helpful, cheers

Does it have the CAT on?

One important thing to do is to take it for a thrash before the MOT, give it some stick. Does wonders to clean the emissions

[dee_RS_2ltr]

lol l'll try that mate! not sure about the CAT l'll check it.

[Kartracer69]

hmm not sure if this applies or if it will help but if your lambda sensor is shot then you're emissions will be far too high, wouldn't be a bad idea to check when it was last replaced, if ever

think that was changed recently mate.

[sailorbob]

If the HEGO sensor was changed was the battery disconnected too? When you change the sensor you need to clear the ecu's KAM memory so it can adapt to the new sensor.

The same thing goes for pretty much all sensors on the EEC-iv as supposedly identical sensors can vary by up to 15% on their outputs.

some useful info there matey. i didn't change it myself, a tuner fitted it so i dont know what he did.

Half an hour of giving my peugeot death on way to test station, and then sitting with it at 2500rpm before the test to keep it warm got it through the emissions - The tester was laughing but said it woould have failed otherwise!

[dee_RS_2ltr]

i'll try that then guys. cheers

THE ONLY THING I COULD DO TO MY LAST RST WAS TO SELL IT BEFORE THE MOT 12% ON IDLE WAS A NO NO FOR THE MOT

is it actually running rich, or are the CO emissions too high because your not running a cat, there is a big difference

[dee_RS_2ltr]

erm, i dont know if its meant to have a cat or not. its got a straight through exhust system on i know that much its a K reg, is it meant to have a cat and how can you tell if it got one? it sounds dumb i know but ive never had a car with a cat on before.

[FiL_FeZ]

What can i do to lower emissions??

dont start the car!

[dee_RS_2ltr]

har dee har har,........not

[FezzR]

are they test the car under cat. regs or not?

[dee_RS_2ltr]

my mate now works for a garage and im gona let him do my mot. he said he'll see if its meant to have a cat or not, and test it with and without cat on the computer thing and see what happens.

[FezzR]

what engine was in the car originally, did that have a cat?
if yes then there is no getting away from it,
if no your in luck

[dee_RS_2ltr]

it had a 1.8 in originally but i bought it with the 2.0 in already. i bought it off sloth from this site last year. but its been in the garage for 6 months not really been driven.

[FezzR]

well as far as i know all zetecs came fitted with a cat so will be tested as such

[dee_RS_2ltr]

ok cheers fezzR

[dee_RS_2ltr]

It passed the emissions test no problem!! PHEW jst failed on leaking shock and a bit of welding lol.

Good news

[Liebo]

I think Cat testing goes on the registration number of the car. August 1992 and on (I think) required a Cat.

Wymm's "No Smoke" got mine through the MOT...

[Fiestasi-Andy]

i put a sponge in my piperx filter worked a treat

Ran s**t tho

[Rhinopower]

what injectors u running? should be matching the ecu!

[dee_RS_2ltr]

cheers guys, thanks for all your help!
