hi guys, hope someone can help me out here?

i have a 93` impreza turbo, just put it in for its mot and failed on high emissions VERY high! fast idle @2500rpm test was 5.079% on the co2!..even tick failed at 1.73%

just changed the maf and had a gas test done tick over gone right down 0.03% bit to low if anything...but fast idle was still way to high 4-5%

any help would be great!

thanks

if only!....all the good places round here got busted....cant find any others so far?....plus im sure im down on power and that does bug me!
