I got my first Subaru the other day for dirt cheap. It's an automatic '97 Legacy GT with an EJ25 with 173xxx miles. It is pulling several codes, O2 Sensor, a fuel temperature code, and an EGR code. It has some universal Borla muffler (with a crack in it) attached to a Home-Depot-home-made midpipe that eliminates the cat, loads of piston slap and a misfire in cylinder one, horribly installed HIDs, and a Weapon R intake that is pulling oil through the PCV. Are there any tips you can give me to make this car work? I am going to clean out the EGR with some carb cleaner, add in the catalytic converter that was eliminated, use some Lucas and 10w-40 to aid the piston slap, and replace the fuel pump (supposedly the fuel temperature sensor is embedded in the pump?).
I am thinking about rebuilding the engine because the piston slap is pretty awful. I am also hoping to eventually do a manual transmission swap.
I know I am covering a lot with this thread, but are there any tricks or things you guys and gals could offer with my problems?
