Over-Oiled K&N Drop in Filter

[MIAMIRAPTA]

Hey guys, sorry if this has been covered but I was unable to locate a specific thread on it.

Anyways, I believe I managed to over-oil a K&N drop in filter that I've had in the truck for a few months now. Had no issues for the first 24 hours after cleaning... but after some full throttle pulls the following day, I noticed the motor starting to bog down under acceleration. Got the truck home, discovered what I had done wrong, and dropped the stock paper filter back in.

This corrected a lot of the problem but the truck will still idle rough at start and stutters under heavy acceleration. I've wiped off the MAF sensor but I am planning on picking up some cleaner for it tomorrow. Any one else managed to do this or have any suggestions for correcting it?

Thanks in advance.

Be careful with that MAF even wiping can screw it up or touching it with your fingers and leaving finger print oil on it.

I would do a battery reset for 15 minutes more if you have the time.
This will reset the values in the PCM it has learned and force a new clean learning cycle.

Seafoam.

Electrical contact cleaner for the sensor.

I agree with the electric contact cleaner for the MAF.

I have taken sea foam, put it in a pump spray bottle, took off the air intake track on my boat to expose the throttle body, start it up, then spray sea foam on the throttle plate. It sucks it in and will clean out the oil residue. Just be JUDICIOUS with the amount you spray at a time. One or two pumps, let it digest settle out, then do it again.

Repeat as required just don't go nuts with it. And let the motor settle down between sprays.

Clean your intake tract with degreaser or sea foam on a rag to get the oil that is stuck in there as well.

I did this on a FI boat that had an over oiled K&N on it and it worked like a champ cleaning up the throttle body.

Go have the BG treatment performed through the intake. Don't be stupid next time!!


















Yes I did that too 25 years ago lol...

 

[Huck]

Or just buy the maf cleaner.

That is just fine and dandy unless the oil after getting hot and the mist gets into the TB and intake..... Something to think about--don't be a cheapskate-most likely need to be cleaned anyway unless you run a catch can.

Boss Hoss - That is just fine and dandy unless the oil after getting hot and the mist gets into the TB and intake.....

Oil mist from the filter has little to no affect on the throttle body and intake and the issues and timeframe that the O/P was experiencing.

Something to think about--don't be a cheapskate-most likely need to be cleaned anyway

Cleaning the MAF sensor isn't being a "cheapskate", it's just part of a routine maintence (especially for those with oiled air filters). Cleaning the throttle body with obnoxious chemicals (e.g. carburetor cleaner) isn't recommended due the possibility of deteriorating the coating in it. And unless the butterfly valve has a residue buildup there wouldn't be any need to clean it. A cleaning of the intake is possible using products designed for that purpose.

...unless you run a catch can.

An oil catch can is associated with the PCV system and technically it's not part of the air intake system though the PCV does siphon-off crankcase fumes and is plumbed to the intake manifold. Again ... A cleaning of the intake is possible using products designed for that purpose.
