Based on some other threads about throttle response, I checked the MAF ground voltage relative to the battery ground. I found with the ignition key on, I got 47mV from the MAF to battery (chassis ground) and around 28mV with the engine idling.

I've read that if the voltage level between the grounds is too high, it could cause some hesitation in power.

Some people have added a ground wire from the MAF to the battery. From looking at the MAF connector, I don't see how this is easily done. To test the voltage, I had to jam the meter probe into the connector, basically squishing the rubbery insulation at the connector end to get a contact on the pin.

I'd appreciate any tips or pics of how people did the grounding. Is there a "clean" way to do it?

razor blade and carefully slice off a little section of insulation off the wire then wrap a similar gauge wire over it and solder. then you can wrap some electric tape around the splice and ground the other end of the wire somewhere. thats what I did.

did I miss something here? is the K&N oil causing damage to a lot of people's MAFs??? I would really like to know since i recently bought a new filter (intake) for the car and dont want to drop money on an expensive MAF! Thanks!

that also happen to me with my mustang after that i only us the cone filter with out oil.

well a lot of people have hesitation problems that they dont know whats causing it and i bet half of them are using oiled filters. i was told by just about all the nissan mechanics that the oil coats the wire and once it does that your basically shot and forced to buy a new maf. they made me spray down both of mine to see if that helps and it usually does for a day but then its back to normal.

As far as spraying down the MAF to clean up the oils, is it damaging in any way? Could it make the problem worse or damage the MAF more heavily?

shouldnt hurt it unless you use a harsh solvent

Thanks for the info.
Did you notice any help in the hot weather by spraying down the MAF?

maybe buy some electric motor spray from a RC hobby shop, that spray is specifically made for electrics
