My 2000 4L OHV has only 65k miles. It runs fine except: after it warms up, it idles a little rough at around 700. It misses occasionally - sometimes it runs perfect, sometimes 3-5 misses in 10 seconds, once or twice over the last month it even stalled.

It starts fine, has decent power and gas mileage. I think it does slightly better when the AC is on - but that could be my imagination.

Problem started soon after I changed the spark plugs and wires.
I've checked for vacuum leaks, and not found any - I may have overlooked something.
I'm not getting any engine codes, and it recently passed inspection with no problems.
I did check the Mass Air Sensor by disconnecting - it stalled when disconnected, as expected.

Where should I look? Thanks!
