Check your fuel pressure. Do you have stock injectors, turbo ect. Do a leak down test. You are dumping fuel, as I am sure you know, this is the cause for the black plugs.

Its a Stock SR with FMIC

370cc Injectors New Stock FPR

Coolant temp sensor? Cheap and easy, take one more thing of your list to check-Im replacing mine next week.

[blacksrjdm]

Ya, was just searching around on the Nissan Assist and the SR20DE sentras had a drivability problem and the temp sensor seems to be the culprit there also. Coolant Temp Sensor.

I replaced that a while ago hmmm i has warranty

[rc1honda]

CTS sensor could be the problem. But .35 seems like a big gap, maybe you gettin spark blow out. I have mine gapped to .22.

[ZOMG.SR20]

ill drop it down to .30 and see what happens

[mRodiek]

If you already replaced the CTS I wouldnt worry about it, mine are gapped at .28 but thats not going to solve your problem.

Did you check the IACV screw?

[ZOMG.SR20]

yes but it was idling fine for 15 minutes at 800 rpm the all of a sudden it dropped to 500 then i hit the gas pedal and it stalled

tryed to start it back up and nothing

[mRodiek]

Replace the throttle position sensor? Running out of ideas lol

[ZOMG.SR20]

i tested that with the multi meter and it checked out fine

[mRodiek]

Injector O-Rings could be bad, another cheap possible solution. Maybe even your fuel pump.

Well yor running rich for some reason. Do you have a fuel pressure gauge?You bought a new FPR but did you set the base fuel pressure? I think the base FP is 38psi. if you base FPR is high you going to run rich. How does the car run in boost? Does it pop at all and break up? Also check your injectors O-rings and fuel pump. Also do a real quick check on the FPR by pulling the Vac sorurce off the FPR. IF there is gas in the vac line then your FPR is faulty and will pour gas into the motor.

[ZOMG.SR20]

no popping the fuel pump is new also and i already replaced the o rings

the FPR is a OEM

[ZOMG.SR20]

b4 i was getting no fuel which was linked to a kink in my fuel supply line before the filter

I have a 300zxTT fuelie btw

[mRodiek]

^^ Set the base fuel pressure, if thats not it then its prolly something to do with your ECU

[ZOMG.SR20]

how do you set the base fuel pressure with a stock FPR?

[mRodiek]

Take it off and buy an aftermarket one? Lol other than that idk homez

[xX RB Xx]

i dont know about the stock one but there is a screw on the top like this on, a nismo fuel pressure regulator,

you screw it up for more fuel and screw it down for less fuel.

Injector o-rings. Very common issue. very easy fix.

[ZOMG.SR20]
