Warning: K&N Filters leaving excess oil on MAF

Warning: K&N Filters --update --bad starter??
Update on latest post. Seems to be bad starter. Probably will buy remanuf.
So i thought i'd tune up my car a bit and replace the filters with K&N yesterday.
Now, The car wont start and has a weird crank and reads CHECK VSC. Had to get it towed back. 2am.
I researched the issue and it seems to be common with K&N filters leaving excess oil on MAF and often just needs to be cleaned off.
I'm gonna grab some cleaner tomorrow once the store opens, and see if thats all it is...hopefully.
Just thought I'd share to see if any one had same issue here and to also warn future buyers. Google "K&N Check VSC" and you will see pages.

How long have you been running you K&Ns? I've had mines on for about 2 years now and have had no issues. Whenever I clean them, I re-spray them and tap against something to get the excess off. This is good info thought and might have to look at my MAF.

Clean MAF, nothing. Engine has cranking sound. never heard anything like it.
2yr nissan mechanic buddy of mine said it's probably the throttle body and manifold that has too much grease and to just clean. any idea?
unfortunately i've been distracted by the beautiful cars here and have only researched relative issues.
Thanks for the note. I'll be sure to know what to look for now.

I have had a K&N on my 2002 since 800 miles (now 126,000) with no issues. I have also wiped the inside of the air passages downstream of the filter and found nothing.

VNTR, perhaps you were oiling both sides of the filter and should just be oiling the front?? Or did you just put them right in out of the box?
i don't know, because i haven't had to oil them yet and shouldn't ever have to. . .

They do come over oiled sometimes from the factory. That's why it's a good idea to blow off the excess with compressed air, or tap the excess off. Some people also over oil them when cleaning/oil the filter with the recharge kit. Usually all you have to do is clean the maf sensor with a maf sensor specific cleaner. Would like an update from the original poster on what the cause and fix was.

Thanks a lot for your input guys.
I DID NOT add any oil to the filter. It came pre oiled and my common sense thought it was a bit oily, though out of ignorance, I assumed a drop in filter wouldn't kill my engine out of the box.
Called lexus regarding valve recall and it was already replaced. It is not related to this issue I don't believe any more.
I've read a lot online about fuel pumps and injectors being clogged by the oil and it solved the issue after replacement.
Dumb question - how many fuel injectors do we have? Couldn't google it.
I'll have to post a video on youtube soon to show the crank sound.

I had a mechanic come check it out and he said it's more than likely that starter.
I youtube'd a gs300 bad starter and the sound was the same.
I've researched and it seems a few members have had to replace their starter as well.
I've very sure its the starter and am looking to replace it myself.
any tip or threads?
