    Help with a CEL!!

    I see that there are other postings for a CEL 420 but most of them talk about adding a resistor for the fix. I would rather do it the right way. I just got a 02 WRX. It had a 4" catless down pipe, a Magnaflow exhaust and a turbo XS BOV. I was having after fire problems so I went back to a stock BOV and replaced the cheap intake with a K&N Typhoon. The next day I got a CEL 420 with a 546. I was about to get a cobb access port and take it to a stage 2 but don't want to waste the money if I need to go another way. Anyone have any ideas??????

    No need for the resistor. The P0420 is due to the removal of the cat. The AccessPort will suppress O2 error codes like this. I highly recommend purchasing the AP and going to the Stage 2 map.

    As for the P0546 try this link for more info http://www.fastwrx.com/p0exgastesec.html it explains why you got that. The AP should suppress this as well.
