Engine/Power - non turbo (All non turbo Imprezas) Who needs a turbo when you have 2500cc? Cams, intakes, exhausts, etc. The 2.2L and 1.8L Subies are cool too.

I've had a similar experience and it was the spark plugs. It would start but stall within a several seconds. Only other thing may be a fuse.

Does it start and actually run correctly for a sec, or just sorta fire but never enough to really keep going?

I'm going to guess that you have a sensor failure somewhere. When you first start the engine, the ECU is 'running on faith.' It is sort of like reaching for the phone in the dark- you know where it's supposed to be, but it isn't always exactly how it should be. The ECU has pre-programmed fuel and spark curves it uses for a few moments before the sensors come on line, simply assuming everything is working. After a little bit though, it starts to read the sensors for input, and if one of them is off, it can result in malfunctions like stalling. Basically, it's going to have to be diagnosed by someone who is familiar with OBDII engines, unless someone else on the board here can give you a lucky guess.

That should help. Your car is going to start running leaner and losing power though. You should switch to a true cold air intake if possible.

Cobb's intake is the best, but it's expensive and has to be adapted to MAF cars. For 98 and 99s, it's really best to just remove the silencer from the intake and stick with stock. You'll still hear that intake growl at high RPM, and you don't gain much power with an intake anyway.
