hi everyone as you may have seen by a few of my other post im having trouble with my p38 4.0 basically its over fueling loads ive just changed the o2 sensor and maf and still no joy it idles badly about 500 rpm and just stinks of fuel i have no idea now what to try so any ideas help would be much appriciated as dont want to keep chucking money at it i had the coeds read and had no faults other than the lambda sensor not working do i need to reset the ecu or anything ?????

anyone?? really need to get this sorted as it done 40 miles on £80 of fuel????

Not wanting to state the obvious but have you checked that you don`t have a fuel leak or is the sender gauge or fuel needle faulty. Has it actually run out of fuel or showing empty? Just a thought..

When you change any part of the fuel system, maf, o2s etc you need to reset the ecu adaptions. It will eventually sort itself out but can take some miles with the Gems setup. The Thor is a little better but they still need doing.

assuming no detected fuel leaks on injectors ,fuel lines etc would check cam position sensor as this would affect the injection timing worth a look

how do you reset the ecu or does it have to g to a stealer ???

You say the lamda sensor is not working, have you changed this? Do you know how important this is to the fuelling?

Matches... if it's over fueling that badly it shouldn't take much lighting

if you dont change your o2 senser, you risk the burning out of one both of your cats. why dont you get intouch with irishrover, he is over till the weekend..
