ok so a couple days ago i got my clutch installed, got a ses that said something with my EGR, we found the problem and fixed it.
then i got antoher ses, this one is random misfires, we took out the spark plugs and two of them were blown so we replaced them reset the ECU and the ses is back again.
what do u guys think it could be?

 

search. been discussed to death.

 

it seems to be common among 03 My friend got a creader to fix it. It's an electronic do hicky

 

wow, ok there are so many solutions, which one ACTAULLY works, or does it just depend on the car?

 

if you have cams ...that could be the reason on a cold start....other wise erase it again and watch if it comes back......mods??

 

i have been dealing with mitsu on this issue for 6 months... they don't want to fix it and they don't care to even try.

 

i have tbe, act hdss and prostreet flywheel, mbc, flash, intake and thats it. if i get that reflash from the dealership to fix this problem, will it erase my flash from al?

 

yes

 

on my '03, I got the P0300 twice. the second time, my dealer swapped the #3 and #4 injectors around to see if it was an injector related problem. Not sure about that, but the code has never come back - nor have I had any other codes since I put in my intake/exhaust/SAFC2.
