Some dis-connect the battery while they
clean the Maf allowing the ECU to relearn/re-set

Hi all. Is there any chance someone has a picture of the MAF in a 4.5L petrol. So I can see where it is located. Cheers.

Don't know if this has already been discussed - if I don't have the proper bit to undo the screws holding the MAF sensor in, is there any reason why I can't just take out the section of pipe with the MAF in it and spray my CRC MAF cleaner on it? Or should I just buy the bit and stop being a tight**** (rhetorical question really)

Just buy the bit. Its way quicker this way and your less likely to stuff the plastic sections that hold the four nuts in place where you undo the bolts to separate the lid to housing.

Yeah, just got my lazy a** down to supercheap & bought one, can of MAF cleaner too. Bloody thing was spotless & looked brand new anyway. Oh well, now I know.

Still need to do this.
Will get around to it one day.

Thanks for the great instructions and which size bit to buy (T20). Did this on the weekend with no probs and disconnected the battery as well. Cleaner is not the cheapest thing to buy, but 30% off at repco for RACQ special def helped

Cheers

Is there much if any advantage to be gained by doing so?
