I wouldn't worry about the oil pressure changing with the RPM's. A good rule of thumb is a minimum of 10psi for every 1000rpm. And with high mileage you'll see the pressure change like that.
As for the misfire... A random SES light like that means that a sensor is reading an error at that given time. It usually isn't anything major and sometimes will not leave a code in the memory of the ECM. I know some people on here have had problems with the cap and rotors from the normal parts chains (advance, autzone, etc.). It'd be weird if it was that though since you had problems before. How many miles do you have? It might be the dreaded "poppet" injectors sticking. But it's just an un-educated guess. You might be cheaper to take it to a shop and let them sort it out. Unless you have an extrs vehicle and like tinkering with it.

I just looked back thru your earlier posts, Did you change the fuel filter yet? if its close to poss being clogged then you may not be getting the correct fuel amount to the motor.. If ya havent changed that yet, its worth a try, they cost about $10 for a fuel filter.. try that and see what happens,, My blazer gets about 280 miles to a tank .. As long as i drive normal without going crazy... also what type plugs did you use? AC DELCO? and the gap should be 60, its been said quite a few times on this forum about using any other kind of plug in these trucks they run like crappola..
