if anything was going to go wrong on the car, it would be the week before Japfest....( the biggest uk Jap show)
i seafoamed a week ago, seemed to improve the running of the car, went to work all week under hardly any boost and drove the car normal.
forward to yesterday... the car was really hesitant not under boost, first suspected a coil had gone as it was ropey as hell.
got my accessport, code
P0103 MAF sensor circuit high input ON 1 CCM (See DTC P0103
came up.... cleared the code, reset the ECU, re-flashed the last map i had, and hay presto, the hesitantness had disapeared.
i then continued to go up the motorway, car seemed fine until i had a look at the AFR gauge!
under boost the car should read 11.5 on the AFR. now under gentle throttle( not even boost) the AFR is reading 10.00 ! ( wont go no lower) i was doing 7mpg at 70mph on the motorway at some stages....

sugestions please as what could be the cause, MazdaManiac (as was always going to be the case) isnt mapping till after Japfest and is pretty much uncontactable.

the only thing i can think of is the seafoam has cleaned the injectors and pump to like new and has made the fuel all over the place, or could it be this MAF problem which i have put the code up for?
the fault hasn't re-appeared since i reset the ecu and re-loaded the last map...

any help would be greatfuly recieved as i think im not otherwise going to get this sorted till after Japfest
