i have a nova gte 1600 8v. but had my car on a gas analysier to check emmisions cause its using a full tank of fuel in 180 mile :( at idle its fine sits at 0.8 co. but fast idle its 9.5 :( and the hidrocrabins is far too high.

i have replaced the coolant temp sensor, and air mass metre and ecu. tryed playing about with the mixture screw on the air mass metre still the same. ive changed the spark plugs and checked the ignition timing. i have even tryed clamping a feul pipe to see if it makes a diffrence and still the same.

i have changed the oil because it is washing the bores becuase it is overfeuling so bad. even when u dissconnect the rocker breather it makes no diffrence.

just wondering what else it could be. any one had any problems like this. all info is much aprreacted:thumb:

Have you made sure the pipe to the afm isn't split?

ARE YOUR INJECTORS OK?
