Soccerstudd5 Posted October 28, 2009 Share Posted October 28, 2009 I have a 94 5 speed and have been looking into getting a CAI for it soon. I had to replace the headlight bulb on the driver side today, so while I was there I started looking at the stock air box and decided to remove the tube coming out of the front of it that just narrows and ends on top of the radiator in order to get some more air flow. Can definitely tell that it's getting more air flow, but it's now running rich, puffing black smoke, and stalling intermittently. Half the time, it will idle fine while in N, and then sometimes it just starts to act up and even died a couple times. Checked the codes and got 55- No Malfunction. Any thoughts? Surely taking out that tube wasn't that big of a deal, how can it be any different from a CAI? Here's some pics of what I did. Also, thoughts on removing the resonator? Do I have to take the whole fender off to do it? Link to comment Share on other sites More sharing options...
adamzan Posted October 28, 2009 Share Posted October 28, 2009 Wiggle the wire on your MAF sensor. I'm willing to bet that's it. Removing that pipe shouldn't have done that. Link to comment Share on other sites More sharing options...
Soccerstudd5 Posted October 29, 2009 Author Share Posted October 29, 2009 Ok, I'll give that a try in the morning. I just went to get dinner and it ran like crap! Had to keep the outside of my foot on the gas while stopped so it wouldn't die... Link to comment Share on other sites More sharing options...
Soccerstudd5 Posted October 29, 2009 Author Share Posted October 29, 2009 Thanks for the info adamzan. Messed with the wires before I left the apartment this morning and it seemed to run fine. Haven't driven it again yet, but I think that did the trick. Link to comment Share on other sites More sharing options...
Precise1 Posted October 29, 2009 Share Posted October 29, 2009 The sharp bend of the wires into the top of the connector is a common point of issue. B Link to comment Share on other sites More sharing options...
BrSurfer Posted October 29, 2009 Share Posted October 29, 2009 I had this same problem some time ago. Same fix, it seems that those wires in the MAF connector are a little short. Link to comment Share on other sites More sharing options...
Terrano1992 Posted October 29, 2009 Share Posted October 29, 2009 it seems that those wires in the MAF connector are a little short. MAF sensor can work in any position (upside down, for example). So, unscrew MAF from filter box, rotate it to a more suitable position (to release tension and sharp bend from a MAF harness) and screw back. Easy fix to a very common problem, yeah?

Kingman Posted October 29, 2009 Share Posted October 29, 2009 I think there's only 3 screws holding it in though, 2 on top and 1 on the bottom, so only one position will work. At least the TBI ones are 3 screws, maybe they went to a 4 screw set up with the MPFIs. Link to comment Share on other sites More sharing options...
Soccerstudd5 Posted October 29, 2009 Author Share Posted October 29, 2009 Good to know. But I think what happened is when I lifted the air box, I did push it out of the way without disconnecting anything... so that probably screwed up the wires a bit. Drove it to the store and home and never had an issue... considering it problem solved.... unless it starts acting up again. Thanks for the help guys!

Thanks for the help guys! that was exactly what I was thinking as I read this, you unknowingly juggled the wires. Terrano92 also gives some great advice, rotate it 90 degrees to the left and you shoudl be golden. Link to comment Share on other sites More sharing options...
Terrano1992 Posted October 30, 2009 Share Posted October 30, 2009 I think there's only 3 screws holding it in though, 2 on top and 1 on the bottom, so only one position will work. At least the TBI ones are 3 screws, maybe they went to a 4 screw set up with the MPFIs. I suggest to rotate MAF air duct (short metal tube with 4-bolt flange, bolted to air filter box), not a sensor itself (small black plastic box at the side of this tube). We are talking about MPFI (VG30E), of course. TBI (VG30i) design is totally different. Link to comment Share on other sites More sharing options...
