Unhappy No More Love.

Well, I went for it, and tried to install a CAI today. Now, the car doesn't want to start. It just kinda fizzle fizzles and then dies. Blown MAF? I'll cry if that's it. There's a wire, though, that looks like a ground wire that should be plugged in somewhere. It is near the vacuum control sensor near the passenger side strut tower. I'll take a picture as soon as my digital camera has enough charge to take one. If anybody can lend some advice, I'd greatly greatly appreciate it. By the way, I have a cursed MY99.

Forget to reconnect the MAF? No MAF sensor == car no workie.

i'd say that's prolly the MAF connector...you did plug it back in and make all the hose clamps tight right??

This wire just looks like a ground wire. It's just bolted onto the metal piece, and not actually hooked up to anything. My impression was that the MAF wires are the 4 wires that can be seen above with the gray connector.

Dont worry about that wire. I know it sounds screwey, but my father has a 99RS, that I always wondered where that wire should go, but never had any problems, so I didnt care. I had a 01RS that I recently traded in for my WRX, and I had that very same wire just hanging there, and again, never caused any problems. So, dont worry about it. As for the no start condition, check to see if the MAF connector is in all the way. Also, on the 99, some came with an air filter in the box by the throttle body and one by the MAF (at least my father's car had both). You need to keep the one in front of the MAF, but if you simply remove the filter in the second box, your car wont start- you need to get the gasket for the second box. You probably already know this, and if you don't- now you do.

Hope this helped some

OK, thanks guys for the advice. I've solved my "MAF" problem. Instead of spending $50 on the gasket for the air plenium, I cut out the filter element, with the exception of a few ribs in the middle for structure. As it turns out, my problem was that I hadn't closed the air plenium all the way, and there was a leak. The car runs now, although I'll do another ECU reset tomorrow, since the car died on the first 4 starts or so. Thanks dan for giving me the idea to check the plenium. I still have no idea what that wire is for.

On another note, I wonder why that second filter even exists. On taking apart the intake, I noticed that the MAF has what looks like a little screen in front of it, so in other words, I see absolutely no way that anything can get through the first filter AND the MAF screen. Things that make you go hmm.....

Silverscooby27- No problem. I'm glad things worked out for you. As far as having two filters- I see no point. But what is even weirder is that SOME 99s had two filters, some didnt, and came with the gasket for the plenum- go figure. Now you might even get some better MPG, I know my father did. Also, I dont know what type of gas you are using, but my fathers car always pinged on 87. Now he is using 93, and no more pinging.

my friend with a firebird has a maf sensor and he had the same mesh grill thing attached to the maf and he took his out. i suppose it's there because the maf is super sensitive and it's there for some more added protection but it's not like it's even that fine of a mesh so i don't know if it could be taken out or not. i dont think much would be gained from taking it out though so i'm leaving mine in for now. u can try and see what happens if you take it out if you want though =P report the details if you do.
