Hi Guys Peugeot 306 XL petrol 1994 My problem is that a few weeks ago my when I turned the engine off there was puffs of smoke coming from under the bonnet when I opened it up there was smoke coming from, what I think is a sensor set into the carburettor body, as you look at the carb from the front of the car its to the left of centre between the stepper motor and the bracket that carries the throttle adjustment its about 3/4” dia pressed into the carburettor body, the smoking was the result of a bad earth to the engine. Since then I keep getting a “engine failure” light coming on intermittently and sometimes it either cuts or doesn’t want to start, then ignition off, try again and it starts fine, this may only happen once a day. Can anybody tell me what the sensor is and what it does how to replace it and how to stop the warning light Cheers in advance
