Alright... well I finally got it all fixed. The car seemed to be running okay. As I said I had installed a new Oxygen sensor. Upon doing checks of the engine, I realized, some how, the wires in the new sensor had touched, and fried. I fixed the wiring and the car began back-firing again. Puzzled, I ...

Pulled everything apart, re-did the timing, although I'm pretty sure it was already correct. The engine continued to back-fire in the intake box... I kept getting the codes oxygen sensor, or idle switch, or air control valve... I rewired the oxygen sensor (which was a new, "universal" bosc...

Oh... and it keeps backfiring in the intake box.

Well, I plugged in the cables to clear the codes, and it immediately started flashing a code. It was Code 35, Canister Purge Valve Solenoid.... I replaced it. I then got code 22, Knock sensor... which was all cracked, so I also replaced. Now it will clear... I'll run the active diagnostic tomorrow. ...

Well, I connected the stock airbox back along with a MAF I pulled from the junk-yard. The idle was incredible low (Under 500, at the first bar above 0) and died if I didn't rev it. The intake also was backfiring. I ran the codes.. and I got a lot of them. In order: Code 42: Idle switch Abnormal volt...

The CEL has been on since I bought the car, its always been on. I've only plugged in the plugs and checked for codes once, before the top-end rebuild. Never bothered to do it again. I will attach the stock box and pull another MAF while i'm at the junk-yard. Plugs are brand new. Iridium Pulse Plugs....

I might have multiple problems going on here so, I'll just start from the top, sorry for a long post. So, after a top-end rebuild to my 91' EJ22 (No Turbo) last winter, I added a K&N filter and removed the stock airbox. I noticed occasionally my idle sinking to like 500RPM and the car sounding l...

Those pictures will help out a lot, thank you so much!

Found a very tiny schematic of it at the bottom of one of my Chilton Pages!

I've looked through all the PDFs... but to no avail. It only shows adjusting, and the side view is always drawn...

So... I have a 91 Legacy Wagon (2.2. Non Turbo). I am currently in the process of replacing the head-gaskets, its a cheap car, and I enjoy learning and working on them so... anyway. I was removing the Throttle body and intake, I started disconnected blow-by hoses and such, and disconnected the gas l...

Just to let everyone know (and anyone in the future who searches this thread with similar problems) It was in-fact, a blown head gasket. I tried burping the radiator like told, but the fluid never dropped, as I seemed to have filled it correctly the first time. It came down to it either being a head...

Thanks for your reply. Theres 270,000 miles on the car. I thought it might have been a head-gasket too, but it lacks signs of such. The coolant level remains the same (no leak), theres no oil in the coolant, or vise versa, and theres an old trick, with the radiator cap off, turn the engine on, and o...

So... I recently bought my first Subaru, a 91 Legacy Wagon for $500. I knew it would be a bucket but so far i've encountered larger than expected head-aches. The car ran good the first month or so I had it, the previous owner told me it probably needed a new radiator cap (which I replaced when I dro...
