im looking into an 03 evo and i heard alot about this P0300 code on 03 evos. i was wondering what it is and what it does? i mean i heard that its a misfire problem. but if i were buy the 03 evo and it does have that problem. is there a way i can fix it? and how often does this occur in 03 evos? insight would greatly be appreciated.

 

WOW- Shoudl I be mean?

Mean- Do a search.



Not Mean- I have a 03 and with no mods you might never get a p0300. DO NOT let your dealership flash your ECU with the fix if you plan on getting a performance flash like xflash, or dynoflash. The dealer will lockout your ECU with the P0300 fix.
