MAF sensor
hi hope all is well

i have not had my defender td5 long and im just working my way through it sorting various issues !

the truck seamed sluggish pulling away until i disconnected the MAF sensor though is this doing any damage to the engine ?would anyone recommend replacing the sensor ? the truck was re mapped before i purchased it i believe a stage 1 ? with an EGR delete im also not sure if this is causing any damage to the truck ? i was potentially looking to take her back to standard as i did not really buy the truck to drive fast !

any help would be appreciated

Pulling the plug on the MAF gives the ECU a standard measurement of air flow where as the MAF adjusts it i have run around for years without one doing no damage but with one you get a better drive and fuel economy not that you bought a defender for those things Laughing 110 Td5 Ex Utilities slowly converting into a pop top camper one day

Leave the MAP and EGR delete in place as they drive much better with them. I would and have fitted a new MAF sensor. Again drivers better, uses less fuel, smoother drive. Just fit a quality part not a cheapy
