I have a issue with having to change spark plugs every month, i use NGK BPR6ES gapped .028. I got the 6 bolt swap done (completely rebuilt full longblock) and a big 16 (it holds down 11-13 psi at low boost and about 15-17psi on high, apexi gt spec 3'-3.5' turboback exhaust hahn fmic, turbo xs bov (recirculated) and turbo xs dual stage mbc. I know the fuel pump is upgraded because i can hear it whining loudly. I know when i changed plugs, the car runs good, then about a month-3 months later (depending on how i drive it) it starts to buck and misfire (popping ANNOYING jerks) when i start boosting. I hold 19-21 inches of vaccuum at idle and it spools nicely when i have fresh plugs in there. I dont have an upgraded FPR, or fuel rail or anything as far as that fuel pump. I know fuel cut cant really be possible because one of my vacuum lines on the j pipe for the mbc split one day my boost spiked to 22 psi and car had no trouble flying!!! the only thing that was hurting it was that my clamps on the intercooler pipes could not keep it all togetherr!!! My spark plugs get fouled badly like im talking black all around the electrode and tip of the plug thread. Im wondeirng if a AFPR or a msd ignition box is what could fix my problem but I was wondering if one of you dsm wisemen could help me with this issue. Oh and also if i cruise for too long it brings up the p0300 code for random cylinder misfire, but i know thats because of the 6 bolt swap. any help is much appreciated. :thumb:
 
If your A/F regulator gauge only works at night, you may have it wired wrong. It sounds like its connected to the headlights if it only works at night.

Yeah the car came like this. Ive had to redue alot of the previous owner's stupidity. Vented BOV, completely hacked wiring job on SAFC, a aftermarket fuel pump with no AFPR. Im just trying to get it to where i can have fun and not worry about being stranded on the side of the road AGAIN.

I wasn't aware that TurboXS BOV's can be recirculated. In any case, TB shaft seals are probably only the beginning of your boost leak test venture, follow the directions in this thread for boost leak testing.

thanks for your help i am really an amateur at this and im just here for you guys to help me. Yeah it can be recirculated, they have different adaptors for recirculating or the typical horn shape for venting. To be honest it has never been this bad with the spark plugs until after i put the 3-3.5 inch Apexi GT Spec exhaust on. I know i have boost creep like ive read about here on the forums, but i know it has to be mostly from the boost leaks.

No problem, everyone is an amateur one time or another, hopefully one day you'll return the favor by passing on what you learned to NEW amateurs. Get your boost leak test and FPR overrun taken care of, then read up on how to deal with your boost creep.
