Why i put my MAF screen back in!

[toast]

After i installed my Kool Blue air filter i noticed my car started to have an eratic rough idle and also jurked at about 1500rpms when you let off the gas. I had a feeling on what it was but i was not sure untill today. I intalled a new screen from my dealer and low and behold my idle smoothed out and the jurking at 1500 went away. Plus i do not feel any diffence in the way it runs as far as proforamce wise.

I decided to put mine back in also due to the bad gas mileage.

In my 2002 M5, unlike my 2000 A4, I've noticed my fuel economy isnt as good as it was before I removed the MAF screen. Im going to put mine back in and see if my fuel economy returns.

I was getting 23mpg for a long time, and after removing the MAF screen it dropped to maybe 17-19 around town. Maybe in the 2002s it severely affects the fuel economy somehow :( Hope thats it, I don't like the fuel economy I've been getting. Then again my foot has been on the loud pedal a lot too :D [img]graemlins/burnout.gif[/img]

im getting 25-27 mpg with a mix of town/highway driving with my maf screen out

[greenasgrass]

geez, glad i decided to keep mine in. when you go to take it off, the fact thats its almost impossible to get off kinda discourages you from doing it...

Naa if you know how to get the thing in and out and easily install/remove the spring holding it in, its cake.

I would of kept mine in im sure if it wasnt for nitrous i didnt want a backfire to blow it to pieces and then get sucked up in my intake that would not be pretty

i get 30 on the highway and 20-23 in the city with no maf screen

well my maf screen is in and has never been out.. at least not as long as I have owned my car.. and I get a little bit of a jerk on deceleration sometimes... more like a hiccup than a jerk.. I have just decided to live with it..

[Camarorulz]

I get that same thing- when I let off the gas it "hiccups" and takes the RPM a half a second to go to normal.

I agree completely.

I'm leaving mine out.(I've had it out for several months now) I may lose gas mileage but, that goes with HP gain. :D If I'm not mistaking Dominic made a post that showed his dyno results before and after he removed the MAF screen. It was shown that he made a 5 HP and a 10 ftlbs of torque all the way across the HP and torque line. ;)

would you guys recamend taking it out when i go to the track. if you do could you please explain how to take it out without tering it up and how to put it back in.

[sped214]

I think the gains that are being seen are are the newer, straight throttle bodies. Us older angled throttle body guys are going to experience practically no gains, and more than likely get a rough idle with it out. I would recommend you leave it in, as you have a '96. When mine was out, I noticed no gains, and a significantly rougher idle.

I don't know about the gain part for the 97 and below, and also the 98's. I do know the 99 to 02 should be ok, I think the car that was dyno was a 2000. For the 97 and below, from all the post I have read on this, it seems that it gives a rougher idle like sped214 stated. I agree, since you have a 96 I would keep it in there.
