" maf sensor " seems to be a common fault mate, could have gone at any time, upto you to decide if garage is at fault or not.

yeah you'll ned to do a reset mate as the ecu will still store the fault in the memory even though its been rectified

ok heres goes

first off, dont just reset and go

4.5k is the factory limp mode. it may just be a simple sensor glitch and a reset may sort it, or it may hide a fault.

best bet get it plugged in and find out the fault code and what it is and have it checked out, much safer in the long run

mick's found the fault code already mate. think what he was asking is wether he needs to do a reset after the maf has been replaced or if the ecu would right itself

if you have unplugged the maf sensor then it will show a code 23 even though the sensor is plugged back in.

sounds like a possibility mate. had a problem with mine when i took off the vent cover above the induction kit. it poured down overnight and it wouldn't rev the next morning if i put my foot down until the motor had warmed up and dried out

it should have had a blanking plate with a couple of holes in it to cover the inside of the bonnet vent. i took mine off before i had the problem. the other problem i have now is that i cant remember where i put it when i took it off so i've had to resort to blanking the vent off with gaffer tape.


afraid i aint too sure bout the gearbox oil
