Cone Filter
i've searched and searched, couldn't seem to find this problem, so maybe i'm just clueless. just bought this 86 rx7 gx. air filter was clogged, so i went to buy a new one...$60 cdn. so i figured i'd just buy a cheap cone filter and rig something up. well, i took the air box out, found the air flow sensor. stuck the cone on, obviously there's nowhere for that sensor to plug into now, so i tried to start it...starts then stalls after about 3 seconds. removed the cone, set it all back to the way it was...same problem. does the cpu need to be reset? will this solve my problems? lol, help!

the air flow sensor (air flow meter or mass air flow sensor- 2 other words for it), this needs to be plugged in for the car to read how much air is coming in , if its not plugged in the car wont run .. u need to have that sensor plugged in

Whoa. Okay, look. When you remove the stock air box, and the bottom of the air box, that square thing it was attached to that connects to the piping that goes up the throttle body is the Air Flow Meter. That's the only thing down there. That MUST stay on the ducting, and the plug that goes into it MUST stay plugged in. What you need to do is reattach the AFM (square thing) and then plug that harness back into it. Get a cone filter adapter (I think MazdaTrix sells one) and then put that on the AFM, and attach the cone filter to the adapter. Problem should be fixed. Make sure that the AFM is installed level, and right side up.

you need the MAF installed, without it your car will run like **** or not at all....
making an adapter is basic, flat metel plate, drill holes, weld little tube onto it and drill a hole out....
easy peasy....
:P

ok, i'm going over to try the car. if resetting the cpu doesn't work, what else should i do? could i have "broken" the part where the harness plugs into the air box?

If you're going to do something do it right in the first place. And also make sure you know what you are doing. I say check http://www.iluvmyrx7.com and read their FSM and make sure you're putting it all back together right. Or ask the local guy to help.

well, resetted the computer. still doing the same thing. right before i attempted to install the cone filter, the car was acting a little strange...the rpms were bouncing in between 3 and 4000 rpm. over and over. i took it for a burn, and it seemed to straighten out. so i began installing the filter. i put it all back together properly. the only thing that might have gone wrong is...the connector (not the part on the harness, the part the harness plugs into) i took the screws off of that, pulled it apart "carefully", realized there was a bunch of snug wires in there, so i screwed it back together. is it possible that those wires could have pulled loose, or could all this be fine, and should i be looking somewhere else? what about that "constant" beep. it's like, 15 beeps, really fast. almost sounds like a constant beep. i'd hate to have to tow it to a shop.
