@Easter Bunny[/USER] if i unplug the maf it dies right away. It wont stay running period. L337 thanks for the life advice.

okay i have confirmed that fuel rail pressure sensor reads 0 volts at all times. regardless of throttle pos. im not gonna beat that bush anymore. however my car is running like absolute shit and i am desperate for help. its breaking up super bad STFT are like +20-24 and the exhaust smells like...

Is the rail sensor supposed to be 0 Volts at all times?

I took the injectors out to replace the seals with CS injector seals. While they were out i cleaned the tips with injector cleaner to get the carbon off. but that was like 2 tunes ago.

I took my intake manifold off to get the pressure sensor out to change it and i noticed there is oil covering the hold down for injector 2 and the wire harness connector for injector 2 as well as the injector connector for #3. It looks like maybe the pcv plate is not sealing and venting crank...

91 oct pump gas from cali

Im running ngk 6510 gapped to .025 as recommended by the tuner.

The issue just started suddenly last sunday right before i replaced the turbo. im getting a CEL for a cyl 3 misfire and i can hear little pops at idle like its rich and creating an afterfire when the extra gas hits the exhaust. The wierd thing is the misfire comes at random times. I drove 100+...

Tune has been completed since before the issue arose. Nothing was changed during the tune other than failed parts.

Anyone know why my fuel rail pressure sensor would be reading 0 volts at all times? Im about to tear it appart and see if something is wrong today just wondering if this is abnormal because everything i read says the voltage should vary. I was having some problems with high positive fuel trims...

You heard right.

They were in that order. #2 was the lowest cylinder. I just plugged the intake manifold hole and let the pcv vent to atmosphere and the fuel trims immediately started changing. Now im back to where i was before all this with the ltft at +10 because my MAF was dirty during the tune and i added a...

compression test was 175 150 165 170 i just realized while i was tuning this last time my occ line to the intake manifold was kinked and not allowing the manifold to draw air from it. and just before this all started i un-kinked it. then today i deleted the occ completely to eliminate any...

Okay so im dealing with a slightly lean condition and a cylinder 3 misfire right now. Ive ruled out it being the new turbo i installed because i flagged the misfire the day before the install i have checked every air orifice before the turbo and after the TB and i took them off and reinstalled...

okay i replaced the turbo with a rebuilt one and here is the datalogs from the new turbo

okay so this might get long winded but in short im hyper conscious of the health of my engine and im noticing things in my logs while re tuning for a different setup that dont make sense to me and im just looking for clarification and making speculation based on research that i have done myself...

Oh i see that makes sense

I have no idea. It dosnt need to be longer for any reason i can see. The aftermarket and stock dp flanges dont have a thicker part on that hole so to me it makes no sense.

The dealership didnt even have this diagram or at least noone who could find it.

You sir are a gentleman and a scholar. I could not find this. Thank you
