the obd deader will be ok on your car fella

and the idea of spraying wd 40 around the gaskets is a good one as this will make it miss if you find a leak.

if it plugs into the diagnostic port then whip the fuse cover off and its tucked inside on the left :)

check the vacume hoses on the engine mate, and you need to ahve a fully sealed exhaust as this will knock the emisions out, then also the lambda sensor will hopefully help it.

Mates got a fault code reader that he uses on his Astra, apparently it works on Corsas so i just need to find out where to plug it in... anyone know?

So... im going to replace the lambda

Check for air leaks (still not sure what technique i should use to do this)

Might aswell get some cat cleaner in there?

Anything else?

Lambda is a 23 or 24mm spanner, if the cat is new sounds like it could be a likely candidate

Cat is 7-8 months old, backbox and middle section.

new cat or better still fit 2 cats
:lol: its a pain in the arse emisions. try pull the test rod just a touch out of the exhaust when he is not looking. = pass

Gave it an 'Italian Tune Up' - fucking ragged the tits off it, got to the MOT station and the emissions test was higher than the last time. He rekons there could be an air leak? Need some advice on how to find this air leak, where the most common areas to look are and if im meant to be listening for an air leak or?...

I have drilled my airbox but put my standard air filter back on it for the second test... shall i fit a standard air box?

Second test results

Fast Idle Test
CO Level = 0.91% FAIL
HC Level = 99 ppm PASS
Lambda = 1.05 FAIL

Second Fast Idle Test
CO Level = 1.01 FAIL
HC Level = 172 ppm PASS
Lambda = 1.03 PASS

Natural Idle Test
CO Level = 0.46% PASS

Is it worth replacing the Lambda aswell? Even though its passed on one of them will it make a difference to the other results?

Give it a fucking good hammering

take the airfilter completely off usually puts the emissions down a bit.
Take the car for a beasting before the MOT so the CAT is as hot as possible.
Higher octane fuel reduces emissions as well I think, like tesco 99 as it has 5% bi-ethanol in it which burns with less emissions.

Corsa B 1.4 16v

What will help me with emissions?

my emissions test results are as followed...

Fast Idle Test
CO Level = 0.58% FAIL
HC Level = 103 ppm PASS
Lambda = 1.03 PASS

Second Fast Idle Test
CO Level = 0.72% FAIL
HC Level = 131 ppm PASS
Lambda = 1.04 FAIL

Natural Idle Test
CO Level = 0.50% PASS

I have a k&n panel filter, will changing this back to standard make a difference?
Will the optilex (or however u spell it)... the more expensive fuel help at all?
Any other tips?
