    Check for loose intake hoses and vacuum lines.

    I'm willing to bet MAF sensor. Jiggle it around, disconnect and reconnect. See if that does anything. I had the same problem a couple weeks ago when some idiot from Jiffy Lube checked my air filter and then didn't plug my MAF back in all the way.

    Edit: You also may just need a new MAF.

    Well if you buy it and put it in and it doesn't work you can return it. As long as you don't damage it there is no way they can prove you put it in. Or if you have any friends with WRX's you could borrow one.

    It's quite easy to tell if an electronic part has been installed. You look at the connector and it's plain as day if it's been connected. Most of the time it's not an issue but if they have a strict policy, you may be stuck with th part so there is some risk. Best bet is find a friend...

    Yea if you look close enough... guessing most parts guys won't check. Best and cheapest way would be to borrow obviously.

    How hard is it to check if it has jumped time?

    Your question is pretty subjective. Depends on your mechanical ability and tool compliment.

    Hey 2002WRXWV, did you ever locate the source of your problem? I'm having very similar issues, except I am getting active (blinking) codes for misfire on all cylinders. I already double-checked my timing, so I know it's not that. Will try cleaning both my MAF and IAC sensors tomorrow. If not this, I'll probably have to check my fuel injectors.

    Just for background, just replaced my head gaskets, valves were checked, heads were machined. After getting everything back together, initially had trouble starting, so I replaced both my cam and crank sensors. This got her to fire up, but now I am getting the misfire codes and slightly rough idle, but only sometimes. Any help/guidance is much appreciated.
