    RPM spikes HELP!!

    I am new to this forum and fairly new to the WRX/Performance car scene. I got a 2002 WRX from a friend of mine about four or so months ago. The only routine thing I've had to do is change the brake pads. No problem. I don't know too much about cars but, know much of the standard things to do. A new problem occurred recently and that was the RPM spikes and then lowers when I accellerate *too* fast? It will usually occur in fourth and fifth gears, but, has also in all the others. The RPMs will spike and then fall back down to where they should be. The car doesn't seem to gain any power from this and I also know it is irregular. Also it seems to be losing power in general. I went to the dealership and they guy wanted $90 for a diagnostics check. I don't have a lot of spare money and probably won't for a while. I was hoping someone could help me or give me some ideas and some things to check for. I appreciate it.

    If this happens when you shift, the problem is sloppy footwork.
    I had the same problem when I first got my wrx.

    So you have it in 4th or 5th gear, floor it, and the RPMs rise above the point where they should be for that speed? If so, your clutch is shot (sorry). I'm pretty confident on that being the only potential explanation. Your going to have to baby it until you can get it replaced.

    Damn! Yeah it's not when I shift. My first car was a manual and that's all I like to drive. I appreciate the suggestion but, I know how to shift I think it is the clutch. Any ideas on how much that will cost me or suggestions on aftermarket clutches?

    Get an OEM equivlant or a little stronger if you like. Getting strong (good grabbing clutchs) will almost always mean you'll break a gear.
    0-60 faster then your first sexual experience.

    +1 for OEM.
