I also pulled my plugs out and they were also all BLACK full of Carbon.The tip was brown though.
This indication is CLEARLY showing EXTREMELY RICH because my car has not been tuned yet and this would explain the misfire problems we are both having.
I just recieved my NEW O2 housing from ALipine on Friday so i will be installing it in excatly 2-3 weeks.They were KIND enough to send me a NEW O2 housing BORED OUT with a bigger Flapper.I believe he machined anywhere between 2-5mm to eliminate my Boost creep and hopefully this will rectify the problem.
Once everything is installed i will Dyno my car with the S-AFC and 440cc injectors i have and will post the results for you guys.
Im running SUPER RICH Now because i installed my new Walboro pump and currently im at 32psi at idle and at WOT it hits 90PSI which is so HIGH.
I believe the reason for this is because i dont have a stock regulator in and all i have is the RRFPR from Alpine and tahts whats causing the extreme high pressure.Im installing an AEM 1:1 ratio FPR to eliminate the bouncing of the Fuel pressure at idle.
Anyways i will post results in about 3 weeks exactly and they you guys know
