I do know about the oil from the K+N on the MAF sensor, this is why I make sure not to use to much oil on the K+N. I also make sure that the MAF is clean with the CRC cleaner for MAF sensors.
The stock plugs made it do the same thing. Only thing I have not done is change the Fuel filter. It seems stuck, as I took it to a shop also to have them do it and they could not get the quick connects to come undone on it either, so I guess it will have to actually go to the dealer.
I have one of the scanners, that will read the Data in real time also, I will try to get that and then I can post the data from that on here, when the timing is changing what RPMS/MPH all that information for every sensor in the car.
