Default Help a Scoobie out!JDM

For starters i was having an issue where at high RPM's i would get random sputters/ almost like a fuel cut. I havent yet done coilpacks so i believed that was issue till i was reading a thread on someone with similar issues which resulted in listenning to another member about adding saulder to pins on the MAF cause they get issues over time. I added the saulder and the car wasnt the same again... this resulted in me tracking down a used 22(86)*0AA160 MAF . I then tried it, and turns out they were different as one had 5 pins and the original 4. so i Purchased a genuine subaru 4 pin MAF for $500+ . to take it home and it STILL NOT WORK.
So i try and erase the code 23 from the ecu but...unsuccesful i even did the infamous no battery for 30 min trick...and last of all i started the car without the sensor and plugged it in to notice no change. Help me out guys.

Subaru-"this part is non refundable" opted to test it for me. and this will be done today, latest tomorro

My thoughts: If test fails..
are their any fuses related to the MAF at all?

where do these wires to the MAF come from? -could i have grounded something out or shorted it? what might i have done this to?

The fault code 23 online could be the curcuit too...Anything i could have screwed up?
Could i have screwed up the ECU in toying with it like this?-its still giving me a code and not working correctly....???

HELP

*might be reversed

Well if it was fuel cut wouldn't your car hit a wall basically? I was getting misfiring/sputtering at high boost and that is definitely a problem with the coils. To go off and buy a $500 maf sounds absolutely ridiculous though. Are you on any of the other forums? I thought I saw something on jdmvip about soldering the maf. Just found a thread on WSC but the guys car was fixed.

Ya saldering the MAF was what i thought to be a win win, if it wasnt the problem, so what? well it hooped my sensor and threw an engine code when i did it, thats why i had to get a new MAF but now its still showing the same fault code(23) and i have a new maf...????....???? the coils i intend on doing here soon but i did the solder to see if it "might" have been the problem

your coilpacks are worn out, get new ones or rewire for GD coils

The car was idling and working fine before the code was tossed... I will go
Get them and do the conversion but why would the coilpacks be the issue with a fault code 23?

oh. i didnt read the whole thing, just the part about high rpm sputter

have you tried resetting the ecu AFTER you installed hte new maf?

if so, have you checked the actual wiring harness for the maf for damaged/decayed/frayed wires?

the high rpm stutter issue definitely is indicative of a coil pack issue though, you probably have more than 1 problem going on at once

Ya i did reset it after the new maf was installed... and i noticed that the car is overfuelling now and i think it might be in limp mode and obviously still has the code 23... it doesnt go over say 3000-3300RPM...also it is all over the place for fueling puttering and sometimes not even starting.

wiring harness is good nice and clean connection as far as volts go.

im gonna get the coilpacks right away, but for now the car didnt even start for me today so i pulled the plugs and there was fuel all over them i also noticed that they were a NGK BRK6EIX i believe and the other forums say it should be BRK7EIX

running a heat range 6 plug wont really make much of a difference especially if you're just running stockish boost levels, and it definitely wont cause your car not to start.

the plugs might be wet because of a misfire due to no spark, not necessarily caused by an overfueling issue.

try to tackle it one at a time, first do the coil packs just to get that out of the way, since you'll want to upgrade the coilpacks anyway, and that also rules out one of the possibilities (make sure you get a reputable shop to do it for you though, other wise if they **** it up you could be chasing yourself in circles haha)

next, make sure the new maf you got is the correct one for the car, maybe you made a mistake with cross referencing part numbers? try to borrow a maf from a friend with a jdm gc8 with a known working maf

after that, make sure you have adequate fuel pressure, a faulty FPR could definitely cause hard/no start/ stutters

well today i put it back together once and tried starting, it wanted to fire up and i was hearing one piston firing but it still woulnt crank, the fuel pump is priming i can hear it and im thinking if not coilpack(which take a week from subaru and are $117 a peice) that my injectors are mangled, i was reading that the MAF and injectors go hand and hand and by trying to saulder the MAF maybe i grounded, or shorted something out...the pump is a walbro 255 and its pretty much 2 months old...lol i just want my car going, dam haha

Didn't you buy a new maf though? I don't see how you could be having issues with it if it's new. Buy used coil packs. You can get 4 for $120 I'm sure.
Too bad I just gave away my oem injectors but there are probably a few guys around Edmonton that have a set after going to 550's.

ya i got one right from Suabru, thing is the cars symptoms did change from when the first MAF went after i sauldered it, so i figured it might have been a efective MAF from subaru so I bought one that came off another suby, once i hooked up the slightly used MAF the car didnt start at all with or without the MAF(before it started with MAF disconnected and connected but had no symptom change even when started without conncted and connecting it) so that lead me to pull the plugs to find them covered in fuel, which made me think the issue is spark...I really am not sure, Help me out guys

Maybe you did short something out when you soldered... are all your fuses ok?

If you have fuel on your plugs its gonna be a lack of spark.
Have you checked your coils? Might be time for a coil upgrade.
Can you verify spark when you crank the engine?
Unplug the fuel pump. Pull a coil and put a plug in the coil boot. Have a buddy crank the engine. Depending on your setup you may need to make sure that your coil is grounded. Its a little redneck but if your good on spark you will see your spark plug fire when the engine cranks. If its weak or its not firing consistantly then you have coil issues.

new plugs installed and coilpacks coming from japan(FML) The car started today and was not pissing the fuel out the rear end like it was last time however it still through the fault code "23" which is MAF like i said though the car is running better with the installed MAF then the first symptoms i have, it temporarily allowed me to rev the car normally and then tossed the MAF code and started not being able to rev past 2400 or so....While at idle, the car ran fairly normal i would say, other then the first innitial start...

Does anyone know what else the fault code 23 could be linked to?
could this in anyway relate to the 02 sensor or ECU?

Any other ideas? I get the coilpacks monday...
