to follow up this thread i made last week (which wasn't the least bit helpful ): Need HELP ASAP. 02 sensor related
The other day i installed both front and rear 02 sensors on my 2002 impreza wrx (CEL read 02 sensor malfunction). Well the rex was running fine intially after install, however about 75 miles later (first WOT pull) i hit full boost (14 psi) and when i got to 5-6k rpm (the WRX pulling hard once again) a Check Engine Light started flashing. Immediately i let off the gas and within seconds the light was completely gone . Any idea what could cause this? Any way of detecting what may have thrown a flashing CEL? I bought the car about 5 months ago with the following (i know i know..stupid mods): Injen CAI, turboxs BOV, and hallman pro boost controller. The boost controller is set for 14 psi boost. Basically i'm afraid to take the car anywhere near WOT right now and i'm wondering if anyone had insight as to why a flashing CEL may or may not occur under these conditions.
Also, can someone provide a link (or details) on how to remove an aftermarket boost controller in favor of regulating boost off the stock boost solenoid?
