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.
