Thumbs up I tightened my left rear lugnuts and my CEL went out!

For a month or so I've been having problems with a misfire on the #2 cylinder (see http://i-club.com/forums/showthread....86#post1449186 for details). At the same time, I've been getting an occasional noise from the left rear wheel, which I figured was my wheel bearing going bad.

Well, Friday I was going to be driving a somewhat long distance, so I decided to check the torque on all the lugnuts. Lo and behold, three of them on the left rear were loose!! So, I torqued things back down and away I went.

Since then, my CEL has been out! Could I have discovered some super secret Subaru CEL fix?

Seriously, I'm hoping my misfire has somehow managed to fix itself. I replaced the #2 spark plug and on two mornings since then the CEL was out when I first started the car, but it came on later in the day. This time it's been out since Friday, and that's even after doing a very cold start after the car had sat overnight in 10deg weather in NH. (The misfire CEL first appeared when the cold weather appeared here in CT).

Keep your fingers crossed! And for those of you with CELs triggered by an aftermarket header, go check those lugnuts!!

After installing my header, I made sure to tighten those lugnuts.

Good luck with the CEL...I know how frustrating that can be...

If that CEL comes back, check your muffler bearings

Blinker fluid too

Once I changed to synthetic blinker fluid, I never got another CEL. Turbo spool up is quicker also.

Well, damn, my magic wore off tonight and the CEL came back on. Very strange, I can't ever feel any difference in the way the car is performing, so I don't know why the CEL is being triggered.

slater - I hadn't thought about replacing the stock powerband with a carbon fiber one - that just might do the trick!

Pat,

Did you check the connector on the #2 injector? It may have gotten knocked loose when swapping out the exhausts from the dyno day.

Any exhaust leaks in that area?

How's the connection of the plug wires to the coil pack?

Just rattling some things off the top of my head.
