M reg 1.6 zetec escort high emissions
Ok on taking the car to mot the emissions came out at CO = 3.975 HC = 752 seems way to high to be the cat or the lambda also the temp gauge is not working tryed grounding the plug from the sender unit no joy checked the back of the gauge worked fine so is it posable the the temp gauge runs the auto choke there for over fueling the engine.

You say the temp gauge doesn,t work could it be possible the thermostat is stuck open which would mean the engines running cold which means the auto choke won,t knock off normally if you short the temp switch wire to ground the gauge goes straight over to hot if it does,nt then the gauge is faulty but its usually the switch as far as the high c/o it could be as stated above or some thing as simple as an air cleaner c/o should be under 2.5 these carbs weren,t the best when they came out which type is it if its the v v i would get it overhauled
