05 STi CEL and blinking cruise

TS656577 · 12-31-2012, 05:47 AM

Hey NASIOC. I know that the blinking cruise is a symptom of a CEL. After researching here and google, most people ask the OP what mods are done and if the mod was a TBE, everyone recommended a tune. It has a TBE and TurboXS UTEC (with tune) from the previous owner. I'm guessing it's something with the O2 sensor but if a tune didn't fix it, is there something else I should be looking for? I plan on trying to see if I can get the CEL read somewhere but I'm trying to figure out if I can "aim" my efforts. Does a TBE change where the O2 sensor is placed and maybe stretch the sensor wires that it malfunctions over bumps or something? Thanks in advance NASIOC

EDIT: I forgot to mention, I had driven it about 200 miles with no issue.

Did it just randomly come on, or did you over boost?

just go to an auto parts store, have them pull the code. hard to say what it is, and hard to help without knowing the code.

As mentioned, get the code read, otherwise it could be anything. It's free at Autozone, Napa, Advanced, etc. We can better help you out then. Also fill out your profile.
