emissions test failure

my mk1 clipper just failed its emissions test any ideas of how to get it passed in the re test? cheers

Mine needed a carb/manifold flange as it was leaking air in..

What year is it? My MOT station also struggled with mine as its a 92 and borderline if a CAT should be fitted.

CO or HC? and what values over? The limits are quite generous and are well within the limit for normal running, my best advice is if its high CO to let the garage tweak the mixture there & then, while the gas analyser is sniffing. You'll be guessing yourself. If its not possible to adjust it to pass in 1/4 hour, by all means post more details etc.

high co not sure of the levels garage thats fixing it up going to put some fuel additive in it to reduce levels just pray it works .its a 1991 clipper

Is the garage fixing it or putting in an additive?

garage that has been fixing it( needed new exhaust and more) ( just bought car ) is not an mot garage it goes to a separate garage for mot .its had all the work done to get it through and they said they would add a thing called "forties" to the fuel to reduce co .

i suppose its not fixing the problem its getting it through the mot

"Forte" is a brand of products used by people like Aston Martin and other reputable companies. Its supposed to be one of the bestter ones.

I ran their fuel system cleaner thru mine and and have had nothing but trouble since….. :dontknow:

I'm personally amazed a garage would add some kind of "wonder chemical" to a car as the first step, rather than adjusting the mixture screw.

Sorry to hijack the thread but have you got my pm paul?
