loss of power/idle rough

1985 380se,200,000 miles.recently bot &runs well but idle in park/nuetral is a bit rough. tach shows about 1000rpm. in gear idle sounds much smoother & faster yet only shows 800rpm. from reverse to nuetral is a noticeable recoil/jerk which i feel is due to fast idle.i replaced fuel filter, idle control valve &all vac lines look ok but no difference.also seem to have loss of power under load / on incline. doesn't sputter, just not getting fuel so i end up going 45mph or less on hills. seems to help a bit if i put it in 2nd but its still not the way it should be. i got 20mpg driving it back 1600 miles & it used no oil. any ideas? thanks.
