HELP!! #2 Misfire Code mystery! NEED Wizard!
Hi all again, and again!
I have a 1997 GT Legacy Wgn, with 2.5 Ltr, DOHC. It has 128K miles on it. This car is only 5 months old to me. mostly dealer maintained by last owner, I have ALL the paperwork!
A few weeks ago it's CEL came on.
OK...this made me go to my Buddy's garage, borrow Snap-on Computer OBDII checker, says #2 cylinder has misfire!
When speaking with my buddy....he says "just needs a tune up"...I looked into ALL the paper work I had...it had it's 120K mile service in MArch, 4 new plugs (etc). This IS important to this discussion. So..........we put a set of plug wires in it! Why! Because in it's 128K miles of life, running original plug wires! Cleared code....code came back up in 30 miles!
Ok, maybe it's the Coil PAck! I was in a pinch, don't want to run car with CEL on, Got USED Pack at salvage yard! Installled. Code comes back on in 30 miles or so!
OK.....maybe we should check plug on #2, SO what if there are ALL NEW!! Check plug....had hard time figuring out why it won't come out easily!! WHY? Because it wasn't in all the way! Never had washer on plug crushed!!! Never installed all the way!! OK...so that was yesterday! We thought we had the problem solved!!! Code comes back on this AM!! I go to buddies.......SAME code #2 misfire!! So I reinstalled my old Coil Pack! Here I sit! I'll have 30 miles on it in the morning, I gaurautee that code will come back up!!
I have changed the type of oil in this to GTX (5W30) High Milage! About 1K miles ago. I have also put in a K&N panel filter! I have heard strange things about NOT using a Subee filter....but that throughs a MAF Code!!
ANY IDEAS????????????????????????

Hi!
I just came back from my buddy mechanic. I just put another borrowed coil pack into my car, already threw code. Tomorrow I'll check the code! If it's #3 misfire I'll know it's my coil pack. Because when I had my coil pack...I only got #2 misfire!
Things you might want to try....I've heard of maybe a bad injector, switch your injectors around, see if you get differemt # misfire code. I also had my buddy speak to his buddy, who IS a Subee mechanic only! He said to do a compression check! I did mine they are about 165 lbs.. This engine was rebuilt 45K miles ago, I didn;t own it then. Anyhow, if you get bad #'s, you'll need a valve adjustment, this also throws these codes! Unfortunatly this MIGHT be dealer only! Good luck!! Tell me what you end up with!

NO Check Engine Light!!!
Hi ALL!
I just got my car back from a Subaru speacalist (not Dealer). It ended up being a valve adjustment on cylinder #2. It was TOO tight! Which I've been told is rare, it's usually too loose! Runs fine now! NO Check Engine Light!!!
