02 gt needs help

[stangasm]

i have a problem with my 02 gt and nobody can tell me what is wrong with it though they see it has a problem yesterday we checked it with a snap on scan tool and i was getting aroung 50 psi of fuel pressure at idle going up to close to 60 psi at full throttle and the spark advance was at 40 at idle going up under part throttle and dropping down as low as 7 degrees under full throttle that's a 33 degree drop i think the knock sensor is cutting it back i only run 93 octane gas in it we pulled the plugs all of them are white from running lean i also have gas in my oil like it is flooding out and a major loss of power but the check engine light is not on we detected a misfire around 2000 rpm but not bad enough to turn mil on the car is almost stock with 33,000 miles on it has K&N filter and cat back system
