Flashing MIL, no codes though. *Updated-Repaired*

[MR.MCSICK]

I have a 99 Legacy 2.2. Recently, it's been running a bit rough when it's cold. It still misses when it's warm but not nearly as bad. The Check Engine light flashed about 6 or so times when it was misfiring. I scanned the ECU for any history codes but there weren't any. I checked the plugs and wires and they seemed fine. I have a cold air intake but it's never been a problem before. The filter is clean, I haven't driven through water. Plenty of spark. I really don't know where to go from here and I'm afraid to drive it if it's something serious. Any ideas?

Check the Maf/Map.

I'll have to check that once the weather cooporates. Thanks Legacy89

Make sure you have no vacuum leaks after the MAF. It could be that something is a little loose and lets in unmetered air, but once it warms up and expands, it seals a little better. If you are unable to find a leak, get the intake system smoke tested. It should reveal any leaks fairly quickly.

That sounds like my problem. :P

Well, I'm tired of racking my brain over this. I checked about everything I can imagine. It's going to the shop Monday. I wouldn't rule out some timing trouble though I hope it's not. I'll let you guys know what I find out. Thanks for the help though.

How long have you had those ignition cables? just a tought

If it was flashing about once per second, that is an indication of a severe misfire.

I got the car back from Subaru today. It turns out it was a bad injector o-ring. I just told them to fix it to finish the diagnostics and make sure that was all it was. I didn't want to have to take the car back and pay another diag. fee. I came out to 130 bucks for everything. I'm happy.

The guy was surprised how the compression tested so well with 181k. on the car. I've never had a car with so few problems.
