Hello -
I have a problem... well, more accurately I don't have a problem! I replaced my last air filter last week (one old Donaldson swapped for a new Donaldson of the same appearance and part number). With the new filter, I get a MIL and Reduced Power within a short time idling. If I clear the code it comes right back. If I drive down the road and clear the code while underway, it will not come back again until I am idling.
I yanked the new Donaldson and put in my old dirty one -- problem GONE.
I data logged both filters with regards to MAF and frequency. '
old: 5.4lbs/min at idle of approx 37khz.
new: 5.7lbs/min at same as above.
Max showed the new spiking to 5.93lbs/min and the old maxed to 5.5lbs/min.
IMHO there's no problem here. So I'm thinking that I need to re-scale my stock MAF numbers. Agree? If so... help? :laugh: When I go to my table I match 37khz to 7.10lbs/min, and it confuses me! I was expecting a lower number!!!
Hopefully someone can explain this a little and help?
Thanks in advance!!
