:mepoke: Hey guys. I have a couple problems
I have an S14Sr in an S13. Stage2 Tomei ECU pre tuned, 555cc nismo, DiscoPotato adjustable WaistGate no boost controller I belive its at 12psi right under 1.0 bar i think it spikes. Built motor, I'd feel safe at around 500wheel :hyper:

I'm due for SparkPlugs and Turbo Filter, I aleady ordered them from Phase2.
1) My first problem is Misfire.
Coincidently It started Misfiring after i put on my Fuel Pressure Gauge with a 1/8 adaptor, so naturally i assumed that was the problem untill it sunk in, I used the same size adaptor for my RB25 and it never Misfired.

:tardrim:I was thinking it could be the SparkPlugs for the reason that i know they are due, but when it Misfires and Pulls back it makes me feel like it could be the z32 maf cuz it'll do it under boost at around 3500RPM, or when i jump on the freeway it pulls back at the same RPMs not under boost just normal people driving but only for the first 5mins so ill keep it under 3RPM so it won't pull back. It only Misfires and pulls back when it hasn't been fully wormed up
Another thing I've noticed when i punch it and It Misfires i let off imidietly. The Uego/Wideband reads rich 10.0 before it hits Misfire, when it starts Misfiring it reads around 12.5(always under 13.0) right before i let off. I feel like it's not a fuel problem....???
Could be a leak somewhere also.

2) My next problem is idle
My Idle started Fluxuating. When I'm driving and I put it in Nutral and let it roll to the stop sign or red light the idle drops to abut 800RPMs and than it shoots back up to 1500RPMs for about a second or two and drops to 9000 OR 1000RPM, I know 1RPM isn't normal but when it goes down to 800RPM it bogs but doesn't turn off:goyou:.
It boggs about 75% of the time. When it does i step on the brakes and the it stops bogging, it's taking a fuckn leak on my brake system!? Idk how i would be able to find that:coolugh:.
Also when it starts bogging and i don't have to or want to press the brake, i press this button. The rear window defrost button and it stops bogging. So confusing:facepalm:The Alternator, O2 Sensor!!!?

Another thing i just got a set of front and rear z32 calipers, so I will be selling my q45 as soon as i put the new calipers on, if anyone is interested, I also have drilled and slotted rotors all around. if they don't fit z32 i will be selling the rotors with the q45
That's it guys, I'm not completely clueless... i would like some reasurence though. Thanks to those that help out.
I work at a place that is Phase2 Dealer so if you need something i will hook it up for your help. So if you need anything send your PMs to Zilvia account JBPUSA.
