what governs the fuel/air mixture in my engine?? (not smart asses saying the ECU)
i guess it would be a combination of
air temp sensor (inlet temp)
also what make sensors does the ECU take into account when deciding wheter the auto choke should be on??
my engine is still runing a little rich which is causing the plugs to choke up so i am trying to decide what it could be.
i have no warning lights so i am guessing that nothing has has broken fully but i think that some sensors may be out of tollerence which may be leaving the choke on for longer than needed.
Obviously i expect the autochoke to be on for a good few miles in this cold weather but i am doing 100Miles of motorway driving eachway to work at the mo so the engine has plenty of time to get up to temp but i am losing around 3 MPG and today the plugs were choked up again making it run rough again for the first few miles.
it does seem to be temperature dependant. i.e it was fine untill friday when i was driving home and i lost quite a few MPG and then the car was a bitch to get started on all four pots this morning (the first time it had been started since friday night) obviously friday was rather cold with all the snow.
just for info the plugs where brand new about a month ago
also has anyone else experienced anything like this in cold weather? especially on the 1.6 16V
cheers in advanced
