I have a stock 2002 wrx with 98,000 miles on it. a check engine light came on. It was a vacuum problem ( sorry remeber the code ) found a tear in the inlet pipe at the turbo (pipe from the airbox to the turbo) replaced the pipe,which was a pain in the a!!!!. cleared the code and the car still acts like a misfire( At 3000 to 3500 rpm ) friend said try changing the plugs which i did (NGK iridium bkr6eix gapped at .30 ) the check engin light is gone ( removed battery to change the plugs ) still acts up. Any clue on what to do next?
What should the boost lbs be !!! now it goes up to .010 which i don't recall it doing that befor . thanks for any and all help.
