I just bought a mostly stock '03 wrx wagon for what I think was a steal from the original owner with 111k miles. I knew it had some pre-existing conditions but became stumped after searching for answers to my problems online.
The check engine light ran two codes, P1443 ( by using search function I gather its either possibly loose gas cap or failed vent control solenoid and not worried about it for the time being )
P0420 ( also used search function and found either a bad catalytic converter or o2 sensor and I find this really needs fixed!)
As far as the P0420 is concerned I don't have an aftermarket exhaust system and all cats are still installed. So, which is more likely the culprit? Both are a little pricey. I assume the o2 sensor to replace is the rear sensor? Also, the cat is the one just in front of the tranny correct? Should I put an electronic/mechanical fix as seen in some posts found during a search of the forums? I live in Indiana and there are no emissions testing here at all.
My other issue I have is the tranny makes a growling/grinding sound in all gears. I also searched this and found most people had issues on acceleration or/and decceleration but not both at the same time AND it happens to me while cruising at constant speed. It gets louder the faster I drive and 5th gear seams to be even louder than the first 4. It shifts smoothly into and out of all gears and it feels like the clutch is disengaging completely in between shifts. I checked the tranny dipstick and the fluid looks clear and at the proper level.
Also, anybody live near Fortville/Pendleton area that could offer a little local help would be fantastic. Don't necessarily need any wrenching done just some advice and maybe a quick look over of the car. Willing to trade services for ice cold beer...
