Hello. I just installed a ztube and JWT POP charger on my 04 coupe and now the check engine light wont turn off. Any suggestions as to what the problem may be? I checked to make sure the sensor was on correctly...disconnected and connected it again. Still nothing. Any help would be greatly appreciated.

 

Assuming that everything has been reconnected properly . . . You might try resetting the ECU. That may resolved your issue. Good luck!

 

Beautiful! That solved my problem. Just to be sure i cleand the MAF and throttle body, but that didn't make the light turn off. I did an ECU reset and presto! Thanx man!
