I just replaced the stock air filter with one from K&N. One question is the hose that attaches to the throttle body. I noticed a black plastic screen and a fine mesh metal screen. I removed them both, should I have left them in place? Does it make any difference? Just seemed to me they were restricting airflow? Any opnions or advice is appreciated.

I've done the same. As long as your air cleaner is clean (and also not too oily) and you have no air leaks -- it should protect the engine from anything harmful. A number of companies sell kits that do the same plus remove the air babble and plug the hole that is left by doing so. You just did 90% of that and for a lot less than $120 :lol:

Well, if there is oil on the MAF then resetting won't work. The easiest way is with an OBDII Scan tool -- if you have access to one. If not, here is a quick trick to try -- disconnect the battery for about 5 minutes (you will likely need the radio code and stations re-programmed). If it stays off you are lucky and the problem cleared itself... if not you will need a Porsche PST2 or other OBDII scan tool to see what triggered the MIL.
