I took my car to a garage to get the codes read; here is what they said:-
p2721 - 02 sensor after cat aging
p272d - attitude fuel trim 2 limit reached
p272c - trim 1
The problem is I've taken my car to a few different garages and none of them can pin point a fault, so they re-set the system and the engine management light goes away but comes back about 100 miles later.
This time however, the codes seem to be different, normally it says something about it being 'lean'.
Can anyone help? I really want the car sorted but nobody can seen to find a problem!!!
PS: MAF already been cleaned twice and no air leaks found.
