you have no EGR system. now I am pretty sure the grey plug is the one that needs to be shorted. just get a twist-tie or small paperclip and short the two pins together.

my mpg is, obviously, between 25-31mpg.

your oil sending unit is fine, assuming that can symbol goes out after starting the engine.

The gray plug shown in this picture, tied to the firewall?



I'll try that this weekend, and I'll update here with results. It threw the code during a short drive last night, which I cleared. It did NOT come on this morning on my way to work, which is a longer drive. Still no sign of the knock code. I'm more convinced now that it was simply old gas, as the tank was nearly empty when I bought it and the car had been sitting.

Thank you very much for the help. If any of you ever gets a last gen Impreza (GD chassis), I hope to be able to pay you back in kind.

UPDATE: So I jumped the gray sensor and so far no code. Drove it for long enough to throw it.

Also traced the flickering oil light. It only flickers over bumps. The ghetto wire splice is almost surely the culprit, so I'll get the soldering iron and shrink tubing out and hit it tomorrow or Sunday. Bought some RTV to slap on the block where the seam is above the alternator mount. That should end that little oil leak.

So then the car will be code free and running well instead of code-red and running well. :lol: I'l let you guys know how it goes.

Thank you again for sharing your knowledge with me.
