Motorhead.. we arre fully aware that the MAF screen is for laminar flow of air over the MAF sensor. Please search around on the subject and you will find that it has been discussed and mentioned nearly every time that a person has asked about it.

I'm not sure I understand where you are going with a K&N causing a MAF issue, when the question the poster was asking was... "Do I have a fueling problem"

Definately good information on the ability of a MAF to be dirtier with a K&N vs stock paper filter, not sure it applies in this case though.

motorhead, are you talking about the big screen at the beginning of the throttle body?

So, if I am reading correctly, you have determined that you don't have a fueling problem and were only experiencing traction control issues due to a heavy right foot, correct?

And motorhead, your basic comments on the function of the MAF screen are correct and may actually apply to Black94'* case since he has a stock airbox and the corrugated intake tube, but should not be applied as if everything is black or white. Many people with smooth-walled intake pipes and high volume air needs have noticed benefits from MAF screen removal as their air flow is more laminar. It all depends upon the application as in any modification to stock design.

I did notice improved performance but a shaky idle while the screen was removed. I put it back in to see if it helped the ported intake Bill did for me. Since then, I feel the loss in powr I had while it was out.

Anyhow, I think I solved the initial problem for now, and if it starts again, I'll know since I have a heavy foot most of the time

MAC, do yourself some self-educatin' and search on MAF screen removal. There'* plenty of good information to be had on proper application and potential issues.

The general consensus is that the MAF screen can be removed for a slight performance gain (probably in the neighborhood of 5hp, just at the edge of the threshold for 'feeling it'). If you have a stock airbox, or even a heavily-modified airbox, your idle quality will suffer greatly.
I took it off awhile back to peek at the throttle body, and didn't put it back on because of seeing the tiny little holes that it had. There might of been a slight increase in performance, but I'm not sure. Idle quality DID NOT suffer though. I'm using the orange Fram AirHog Filter.
