Reseting the ECU or not wouldnt cause the problem. Id take the plug for the maf off and put it back on.

hum, '98, I had the same problem at first, I then realized I had bought an intake for a '99 and it did'nt have the correct vacuum line fittings, there was one house coming off the block, or the IAC (I forget which one) that had nothing to connect to... all I did was buy a "T" fitting and pluged it in with the crankcase vent hoses... car started up and ran fine... so yeah, make sure you have ALL the vacuum lines hooked up to something...

basicly, I have the two vent crankcase hoses T'd, then I have those T'd in with the Idle Air Controller then I have those run into the intake... I have the vent coming off the block going into the intake as well... hit me up on AIM if you need more help...

I've seens cars smoke like a chimney when the valve cover vent hose was "T"'d to the Idle Air Control, so it seems you are luckier with the crank case venting.

so you are saying I should leave the crankcase vent hoses open and not connect them to anything? (get a small breather filter) ?

No, just saying that the valve cover vent hose T'd to the IAC will make the motor smoke like an Iraqi Oil Well

Seems like you don't have the same problems T'd into the crank vent...

The oiled foam air filter is superior for trapping dirt on a dusty road.

It has more surface area to trap the dirt, and doesn't restrict air as much when dirty. I plan to ditch my K&N style cone filter for an Amsoil foam cone/pod filter soon because on a trip in the mountains to Cripple Creek the K&N style clogged completely and it wouldn't even idle properly at the end of the drive.

Bratmantlz and I sat there and beat out about half a pound of dirt from the filter to get the car to run properly!

The IAC vacuum hose (from the TB to the intake) MUST be hooked up as the first vacuum line behind (after) the MAF, or the car will not idle. Hook it up after the other vent hoses and you may have a lot of smoke out of the tail pipe.

If you T some other lines together, you can get all 4 connected to the three vacuum nipples, and you'll be okay.

You will NEED to install a bung right behind the MAF for the IAC vacuum line.

If you have an intake NOT made for a MY98 Impreza, you might have a slight problem. I believe they changed things around between the MY98 and MY99's to have a different layout for the intake.

The 98's had the vacuum hoses and the like spaced down the intake, where the earlier years have them at the airbox. If you have a rallispec intake that is made for the 99 and newer, the bungs probably aren't there.

JC Sports (when they were still around and trying to do work) had an intake tube made up that has all the correct bungs on it for the '98. Here's my install of that tubing on my car. The pictures are out of chronological order, but thank ImageStation for that. And yes, the filter is on backwards in those pictures. I have long since corrected this.

The rest of the parts I got from the nice fellow who posted above me, Larry Ganz. Picked the necessary stuff up from his site, ImprezaRS.com. However, it looks like many of those things might be discontinued at his place, so who knows.

Hope you get this worked out, and you may need to put your stock intake back on while you get this straightened out.

ok i'm going to try to make this work. where does the large tube that connects right after the MAF go? also where does the tube that comes off the TB go?

im thinking that i will put on one bung right after the MAF and then use the catchcan.

thanks
will

use the catch can for the other stuff, and run a line from the IAC at the TB to the intake right behind the MAF adapter.

You could drill a hole in the intake just a little smaller than the IAC vacuum line, and smoosh the vacuum line into the hole.

We get short pipe sections with a 1" vacuum nipple made for us, for our 1998 and older intakes, and could sell you one, with two 3x3" silicone connectors and 4 hose clamps to attach it between your intake and MAF adapter for about $89 + S&H. This is basically our 1998 intake minus the filter, the MAF adpter, a hose clamp and bracket. Obviously it is cheaper to do the first option.

It is only the 1999 and older PRM intakes we discontinued, as well will be selling Cobb intake for the MAF models very soon.
