Sounds like your idle air control valve is going bad.  It is located on your throttle body and is held in with two screws.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

Rough idle and stalling


it will have codes but the scanner in use doesn't have the right protocol for reading them
Indicates a faulty ambient air temp or BARO sensor so there will be codes

1990 Honda Accord DX 5 speed no power/2 cylinders not firing?


ok.....as far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on them.now as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB
