Ok i got several questions for vishnu, turbotrix, dynoflash whatever.... i put on an exhaust ( a week ago ) no codes until today.. i personally dont' think its anythign else other then the p0300, i have had this problem....

1)do any reflashes cure this yet???( p0300) also... i am running catless *slap on the wrist*.. if not can this be a potential problem?

2) and i'm wondering will a reflash make sure my check engine light doesnt' come on for lack of a cat? saying i'm putting out polution or whatever??

my friend has a WRX and i know cobb does that and throws no codes cause of the flash... i mean i know in Pa, if your car is a 03 or newer you only have to have OBDII scanner test, and then a visual, BUT i know i can get around the visual...

any help would be great guys thanks a bunch

 

- there is a p0300 flash available from mitsu.. it has mixed results, but worked for me.

- the lack of cat is causing your CEL.

 

well do aftermarket flashes get rid of this lack of cat code??? cause its pretty annoying driving around with a frickin check engine light all day lol


plus why would this light come on a week later??? woudlnt' my car of sensed it like 2 days after getting it???

 

Same prob looking for the same fix

Staton

 

Go out and buy an 18mm spark plug anti fouler, drill out the center to 1/2", screw into 02 bung, screw in 02 sensor. I have been doing this for about 6 months and still no CEL.
