    Thanks for your reply.
    I am reading through different scanner reviews and some aren't compatable with certain Japanese makes. Do you guys have one that you like and has been good to you. I also have
    CRX but pretty sure if that is OBD2...
    It would be nice to find one that covers both...just tihnking outloud.

    Actron Pocketscan. That's what I have. I never checked for compatibility. My buddy had one I tried it and it worked. The codes in the back of the book help. There are also Subaru specific ones: Subaru Trouble Codes - 1996 & newer Subaru-specific OBD-II Trouble Codes

    The Pocketscan is the cheapest and will do the trick, the more expensive ones just have more buttons and will actually display words on what the code is vs just the code.

    This little guy is worth it too for when you go to get your yearly emmisions tests. It will tell you if you have any problems so you don't waste your time at the inspection place being told you have failed!

    I bought the PocketScan today...hooked it up...No codes...hmmm
    The light is off, but I though it may still be stored.
    I will hook it up if it comes on again

    So I changed out the fuel filter and cleaned my MAF sensor (was filthy btw) and the idle is much better. Did both at once, so not sure what fixed it.
    But today the check engine light came on..I scanned it and got the code:

    P0301

    Car feels fine, but the light came on again...2nd time this week.
    I drove 30 minutes, parked, let car sit for 20 minutes, went to start it and it was turning over but not starting. Took 3 tries before it started. The light came on about a mile later.

    Any suggestions?

    That code can be a PITA.

    Have a look through this - see Donkey's first post etc.

    Thank you very much. Excellent reference post.
    Does anyone know how common it is that coil pack go. I did the plugs last year in hope of fixing the problem with no luck.

    I will start going through the list in the meantime.

    BTW, rough idle is back today. It was nice the 1 day it was gone!

    I'm not sure what all problems the IAC valve may cause, you might want to read up on that.

    Seafoam next probably. You can find threads about how to suck it into the motor correctly through the BPV line. Never done it personally so form your own opinion (I wouldn't personally put it in my oil ever). Definitely don't hydro-lock your motor and change the oil when you are done.
