On my '04, with nearly 106K hard miles on her (nearly all at 80 mph, with a 16t front counter sprocket), I'm not getting any oil pressure reading on the gauge at idle, and the Oil Pressure light may flicker brightly unless I keep idle above 1500 rpm (however accurate that stock tach is). Running hard down the freeway at speed, closer to 40 psi. I think it's getting time for a new oil pump.
