120k miles, stock with a oil leak from the top of the motor that seems to progressivley getting worse. Starts fine but runs like crap until warmed up. Codes are P0263 and P2290. Sounds like a Fuel Injector and a ICP sensor?

That oil leak is probably comeing from your ICP or IPR sensor themselves. The 03 ICP was bad for that. The sensor would leak thru the plug and into the harness pig tail which is why when replaceing a leaking ICP it was recomended to change the pigtail at the same time.

As for the injector code try clearing it and retesting see if it comes back.
