01 Type R stock everything. Car idles rough has CEL code for secondary o2, changed plugs they were carbon filled. Put new ones in and withing a week they were black again. Some one told me that the secondary o2 doesnt affect performance, so the o2 wouldnt make the car run rich and act wierd. Yesterday i started the car and it turn off within a minute, then everytime that i would try to start the car it would turn off immediately. I tried for hours to figure it out. I left it for about 2 hrs, then i tried again and after thge 4th time it turned on. Anyone knows what could be the problem?

 

Just a guess, but have you checked your fuel pressure regulator? Sounds like it's gettin way too much fuel.

 

i'll check to see why the car idles rough, check for vaccumm leaks(will change your fuel pressure), timing and etc,

 

just got a fuel pressure guage installed, it reads 43 psi.

 

ok forget to also mention that the type r actually belongs to me was using my buddies acount due to the fact that mine had some issues

 

help anyone
