2002 Impreza outback sport 2.5l H4 help
Looking for some support/advice on some issues im having with my new to me impreza. This is my first subaru, so some of these things may be normal with these cars but im not sure.
Firstly; the transmission/clutch. I changed the tranny fluid which was very black to Royal Purple 75w90, and it shifts ok except for a few things.
1) Going into first at a stop sometimes grinds; which i understand is pretty normal and is solved by going into second, then first.
2) Occasionally when shifting I feel/hear a clunk that seems to be coming from the engine bay right in front of me. Sounds almost like its on the firewall, or perhaps engine mounts?
3) My clutch pedal feels very odd. When I first start driving, the engagement point is very low, and at the bottom is feels almost like its grinding/scraping at a pivot point. The top quarter of the pedal seems to be loose. As I drive the engagement point gets even lower, to the point where full compression feels like its barely disengaging the clutch, and the top 3/4 of the pedal literally does nothing; almost as if it is totally detatched from any return spring it moves so freely, but does stay mostly at the top when i let go. Is this air in my hydraulic system or something else?
Second problem is my CEL P0402; the o2/cat code. I tried the $5 fix with the non foulers, didn't work for my car. I wanted to get some UEL headers and a catback in the future; so should I just go ahead and do that and live with the light? I can't see any way around this browsing through old threads if I want an aftermarket exhaust anyways. Also, is it possible to leave the mid pipe and just get the catback and headers? Or do I need the full system at that point?
Lastly, my car seems to have issues filling; so that points to the evap system. After some research it seemed to be the charcoal canister, so I removed it and inspected it. Weighed 4.5lbs (normal?) and no sign of any pellets, the inside looked in pretty good condition from what I could see. I blew air through each inlet and some air did escape the other ports, but not 100% I would guess. Hoses seemed clear; is there as easy way to test the valves in the evap system?
Any help would be so helpful, I love this car so far but i need to fix these gremlins.
