Hi All,

I have had an engine management light on for some time now flagging lots of u codes (to do with power steering) and p1135 and p0105 so the pre cat lambda sensor and the MAP sensor.

I have changed the lambda sensor and the MAP sensor but after a couple of hundred mile the light came back on with the same faults.

When the light was on previously before changing the MAP sensor the car would do 28 mpg and idle badly with a strong smell of petrol as it was running so rich. Now I have changed the MAP sensor the mpg is up at ~36 as it was before any of my problems.

I went to a garage today and they say the two faults could be linked to an air leak somewhere but they would not tell me any more obviously as they wanted to do the work (robbing b*stards) Anybody got an idea where the air leak could be or how i would test for one?

The second part of stalling seems to happen when going from motorway running to standstill when coming off the motorway. since the MAP sensor has been changed it has been better and the idling is better but still happens occasinally

Any help would be greatly appreciated

Tony
