Hi Guys,

Just need a bit of advice as Massively failed on my emissions today, It is a '98 1.8 Escort GTi with a 2.0 Zetec engine. Results below:

Fast Idle:

CO 2.064% (upto 0.300%) Fail
HC 81ppm (Upto 200ppm) Pass
Lambda 0.949 (0.95-1.09) Fail

Secomd Fast Idle:

CO 2.371% Fail
HC 80ppm Pass
Lambda 0.940 Fail

Natural Idle

CO 0.367% (Upto 500%) Pass.

It was fine last year and the only difference is that it has had a new headgasket and now has a drilled airbox.

Any suggestions please help.
