I have 2.0l turbo wrx wagon before i replaced some stuff ( new timing belt/water pump, net cat converter, and new turbo) it wouldn't build rpm and was very sluggish couldn't even drive down the road today I just had all the new stuff put on and it's still running the same and note this when I went to change timing belt I noticed it had skipped a tooth and also forgot to mention it threw a p0302 before I added all this new stuff and was running fine and the code went Away and didn't come back on so anwsers would be great thanks.
