    hi Barry, checked the pipes today and they seem fine to me. took the car for a good thrash and the codes came back. Once I cleared them and thrashed again with no reaction at all and went very very well. got back to the w/shop and as i was chatting with my number 2 about what had gone on the codes came back at idle?? then when i turned the engine off and reset the codes p2453 came straight back without the engine running? and refuses to clear, i feel a sensor would be a good choice as i have no data to test it although i will check continuity to the ecu on the wires first just in case.

    Also I thought I was loosing the plot as the engine was the same as the 307 in another post I have on here but that is correct it seems, never stop learning in our job eh! obviously we dont do many fords
