DO THIS: --- First, inspect the vehicle for a reuseable aftermarket excessively oiled air filter
DO NOT DO THIS: --- DO NOT repair under warranty if concerns result from the use of a reuseable aftermarket oiled air filter
The installation of an aftermarket reusable, oiled air filter may result in:
^ Service Engine Soon (SES) Light On
^ Transmission shift concerns, slipping and damaged clutch(es) or band(*)
^ Engine driveability concerns, poor acceleration from a stop, limited engine RPM range
The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.
When servicing a vehicle with any of these concerns, be sure to check for the presence of an aftermarket reusable, excessively oiled air filter. The MAF, GPS reading should be compared to a like vehicle with a OEM air box and filter under the same driving conditions to verify the concern.
Transmission or engine driveability concerns that are the result of the installation of an aftermarket reusable, excessively oiled air filter are not considered to be warrantable repair items.

Is there a way that the MAF can be cleaned? It it very easy to remove, but I just don't know if it is easily cleaned...

I can not speak from experience witht eh bonneville, however the folks in the thunderbird club i belong to have known about this kinda thing for several years. The fix is pretty simple. You take out the MAF sensor and use electrical cleaner on it. It should be (if it is the same as a Thunderbird) a thin filament with w small white area on it. If using the spray electrical cleaner doesn't get it completely clean you can usea qtip to help. But you have to be extremely careful not to break the filament or scrape the white surface off. I had some issues with my Tbird when I had it at the dyno. Put down something like 158hp inconsistently. Took it outside cleaned the MAF and put down 162 pretty consistenetly. Not much of a difference, but those are rear wheel numbers, so the actualy engine numbers would be slightly higher... Well worth a looksy to make sure you don't have that problem. Also something of a preventative measure. Next time you clean your K&N, oil it per the instructions and then shake it violently to get all the excess oil off of it prior to installing.

I have used K&N drop-ins on several different vehicles without incident, however, all of those vehicles have had a MAP sensor not a MAF. I'm thinking that this is the reason why I never had the issues. So long as I can clean it myself to see if that is the problem, I'm fine with it. I always apply just enough oil to coat the surface, never lather it on and I usually take my shop vac and suck any excess off (because I'm not a pro at oiling filters by any means). However, when I put in the K&N in my bonnie, I just put it in straight from the box. My issues started showing up not too long after I installed the filter.
Thanks

I have heard that the filters are over oiled from the factory, it has been so long since i have gotten one from the factory I can't say for sure, but the shaking the filter to remove excess oil seems to have worked in my Tbird. Hope cleaning it helps.

We've had a couple fail in this manner, for possibly this reason. When I clean and re-oil mine twice a year, I follow this procedure:
Put a lint-free absorbent rag INSIDE the filter while oiling the outside. Fill the entire filter with the rag. Let it sit for 3-4 hours. After the first day of running, remove the filter and look for any oil residue on the inside of the intake pipe. If you see any, carefully clean the MAF filaments with rubbing alcohol and a Q-tip.
I just did this on Thursday again with good results.
