rediculas fuel consumption!
got a focus st170 drives nice I like it but it is DRINKING petrol! I put £40 in it driving normaly and I got 130 miles out of it! 1st thing I checked was for a leak! but nothing had a scanner to hand so scanned it and nothing. so took it down the road and got an emissions test done. the lambda is up at 1.7 and hc is wayyy up at 0.700!! so clearly this is the problem. I serviced the car only a month ago. new cambelt and waterpump too. ut drives and runs lovely feels fine. what else could cause this ? any ideas also had a new stat aswell just seeing if there anything common on these. I know there juicy anyway etc etc but iv worked it out and im getting 19mpg!!! any ideas ?
