1994 impala ss stock lt1,,,misfire from 4 different cylinders but mis at random...only misses 1700 RPM and down....and is really bad at idle....cleaned injectors and nothing happened....replaced valve seals about three weeks ago and the reason for replacing was oil fouling spark plug on #8 cylinder....car ran good for a day then started missing on #5....took to my buddy to re-adjust rocker arms to make sure i did them right....he said they were good....ive checked spark and resistance in plug wires...next thing im thinking is taking off the distributer cap and checking that but idk....need some opinions please...

Dont panic! Just change your opti. When it takes a dump it begins to have multiple random misfire, if you hook it up to computer you can actually see the misfire jump from one to another cylinder everytime to turn off and on the car.

so is that just cap and rotor or....?????¿¿

No, the opti is the whole distributer. It's kind of a pain to get to, so do it right and do it once- replace the whole thing , and not with a cheapie from e-bay or your local parts store, either.
