hi managed to clear my error code 14, i have a 205 with mi16 motronic 1.3 88-92 now have a code 52 mixture regulation does anyone know what this means i.e what exactly to check, also have code 34 canister purge valve but this has been removed so not plugged in. does this have to be connected for engine to run properly could these 2 codes be related , the code 52 only seams to come on after the car has warmed up a bit, any help would be appreciated thanks magichands

have cleared code 52 by getting ecu repaired £200,

bought a second hand purge valve and plugged it in fault 34 now cleared,even though it is not plumbed in,

thought all was going to be sorted but still lack of power and fault code 31 now showing lead to believe its either a air leak after afm or exhaust leak between block and lamba sensor so will soon no as stripped all the inlet stuff off ready for new gaskets and inspection of pipes ect , then going to check exhaust manifold for cracks as believe this is a common problem with these,

am getting sick of seeing fault codes but only 1 to go.
