How high were they?? It may be just a case of adjusting the AFM but often its a ecu temp sensor problem.

3.6 I believe and 3 was the limit. When you say adjusting the AFM is that like a mixture adjustment screw or something?

Edit due to above posts. limit is 3.5- so you're not far from passing. Turn the screw out. Decent testing centre would have done that for you.

Yeah they really p*ssed me off actually, also failed me on one of my headlights being slightly of aim and both front rubber brake hoses being corroded although having inspected them I can't see any corrosion??????

 

I would have though the majority of places would have also spent a few seconds adjusting the headlight aim.

sure it wasnt the copper lines that have corroded? common fault and not much to replace. Flexis are best to just replace all round with goodridge stuff, not much difference in price.

My local place adjust headlights for a fiver if needed. I keep meaning to mark the garage wall for fuuture alignments.

Nah definately the flexi ones. Already bought the front rubber ones, cost me £17 as you say not much more for the Goodrich but I could only find them in a kit for front and back and I only wanted the fronts.

 

Also have phase 2 rear light lenses grafted onto phase one light clusters which is an MOT failure, when I bought the car the guy gave me the old ones 'for the MOT' but I couldn't understand why so chucked them away now having to buy new ones from ECP for £35 :unsure::D

Anti clockwise leans the mixture and clockwise richens. Hope that helps.

Remove the breather hose thet goes between the intake from the oil filler cap, that could drop your emissions down & its allowed (kinda).

 

Either that or take your car for a good blast & ask them to check the emissions asap when you get to the garage so it is still hot. Leaving the engine running if needed until they do the test.
