the o2 sensor managed to be hitting up against the tranny, and the wire split open and short circuited my SBF fuse. So I just unlpugged to the o2 and replaced the fuse.
Midas did a shitty job on the exhaust. So I am looking around for a new place, or ideas.
I will give that fluid test a shot!

Ah, okay.

Let me know how the vacuum leak test goes. The difference that the spray makes will be very subtle, so listen very carefully.

it made no difference at all. I sprayed anywhere a hose went into a T or elbow or any type of connection. The car starts and idles but any rev causes it to go haywire. even after letting it idle for a bit it still begins to go nuts. Eventually the rpms drop so low the car turns off.

so I have no front o2 sensor, because its unlplugged, so would a bad rear o2 sensor cause this?
I just installed a air/fuel guage about a week ago, and it appears to read the rear o2 fine, but if I dont have a front one for now, and the rear one is bad then maybe my ecu is reading bad or nothing for exhaust flow.

You're using the stock 95 ECU, right? I have no idea how it would respond to having no front sensor and a bad rear sensor, or even no front sensor and no rear sensor.

But you could always try just unplugging the rear sensor.

yeah stock ecu, but the greddy emanage is intalled. And the car has had no front ecu for about a month now with no problems, but if the rear o2 went bad just now, then maybe....

Today I pulled my ngk densos and checked those, quite carbon fouled. I replaced them with nkgs 6s. My bov was leaking so I tightened that.
Turned the car on, it idles great, but I give it gas and boom it bogs, moves, bogs, then shut off. Sounds like a misfire or too much fuel maybe.

Maybe it's something in the e-Manage.

I checked all my settings, look good on the emanage (it has a warning light, if it blinks somethings wrong) but nothing at all.
So I checked all my wires again, and turned the car on. Idled almost perfect. Reved great, went for a ride around the block. I went about 40yrds, made it into 2nd then the car just bogged and turned off.
I am going to replace the fuel filter tmrrw. My egts were a little high, but nothing crazy.

Yeah, replacing the fuel filter sounds sensible.

replaced the fuel filter, and the car ran perfect again. Weirdest thing how so fast the car would go bad like that.
Subarus are just unique I guess. Thanks vrg3 for talking with me. Your sig really does fit you well.

No problem.

I guess some big chunk of crap must have gotten lodged in the filter all at once.

You may want to also check the sock filter at the fuel pump's pickup, just in case.

hmmm good idea, I will. Thanks.
Also would me going to stock NGK 6s compared to NGK Denso helped too. My Densos werent burn't and carbon fouled from just one months of use. Doesnt that mean timing or gap is off?

In general new plugs are better than old ones. Which engine were the Denso plugs specified for?

Not being fouled and burnt after a month isn't a bad thing as far as I can tell, so I don't think it necessarily points to something being off.

I'm not a tuner, though, and your car is something of a Frankenstein setup, so I don't know what exactly you should be doing with spark plugs and spark control.

my mistake I miss typed. The Densos WERE burn't and carbon fouled. They were specified for my car.

Right, I understood what you were saying about them being clean after a month...

They were specified for a 1995 2.2-liter Legacy with a WRX turbo bolted on?

yeah there were made for the 95 Legacy NA. I had them on since the turbo, checked them and were carbon fouled and burnt looking. So I replaced them with Stock Legacy NGK 6s.

Okay... I'm not sure what you're asking, but if I were in your shoes I'd probably start with BKR6E-11 plugs and consider narrowing down the gap and/or switching to BKR7E-11 after some testing.

okay cool. Cuz I did lower the gap on my NGK6e-11s.
Just wanted to confirm.
