So i have a 02 WRX… i was being retarded and running and open BOV for a while… it ran rich and i threw a Check Engine light. I changed my Plugs first off earlier today. i then unplugged my ECU and waited 10 min and plugged it back in. after i went for a test drive and the car is still boggy as hell and sputtering if you go up above 5k. off the line its a dog as well. i went to advanced auto and got the codes read. came up as 4 codes… p0301 Cylinder 1 Misfire detected p0302 cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected p0304 Cylinder 4 Misfire Detected any ideas how to solve this issue? ---

Did you gap the sparkplugs according to specs? Could just be the new sparkplugs. I would put the old plugs back in and see if the car runs better, then you know its the plugs. ---

What kind of plugs did you get? Sounds like they are causing the issue. I wouldn’t go Platinum or Iridium. Get a standard plug, and it won’t foul out as fast. ---

Sounds liek a fuel delivery or spark issue…does that car have coil on plug or one single coil …and do they have MAF sensors
