highwind Posted January 27, 2015 Share Posted January 27, 2015 when i started my 09 legacy the other day my check engine, cruse control, traction control, and my S mode lights all started flashing. when i hooked up my scanner to it i had code p0302, p0304, and p0306 so what would cause this?

GTEASER Posted January 27, 2015 Share Posted January 27, 2015 Did you look up the codes on the internet? They are cylinder 2, 4 and 6 misfires, all on one side of the engine, which is curious. Clear the codes and see if it happens again. Could be coil packs, injectors, some loose wiring, O2 sensor, but odd that its all on the one side of the motor.

highwind Posted January 27, 2015 Author Share Posted January 27, 2015 sorry i forgot to mention that i knew what the codes meant. the weather here has been really wild with going from +4 C to -30 C if that cause an issue. Link to comment Share on other sites More sharing options...
GTEASER Posted January 27, 2015 Share Posted January 27, 2015 With those temps, I suppose it could be a little moisture in the fuel causing the misfire. Did you clear the codes? And have they come back? GTEASER's 2012 Legacy GT - Sold GTEASER's 2009 XTeaser - Sold GTEASER's 1992 Legacy SS - Sold Link to comment Share on other sites More sharing options...
highwind Posted January 27, 2015 Author Share Posted January 27, 2015 i cleared the codes then ran a bottle of royal purple max-clean and nothing has come back which i am thankful for. Link to comment Share on other sites More sharing options...
