My 99 sport 4.0 OHV 120,000 miles has all of a sudden started acting strange.

When I first start it (hot or cold) I notice what seems like a rough run situation but for only the first 1/2 second when it first cranks. It starts fine (first crank) and runs great getting 20 MPG but this very short roughness is new in the past three weeks.

I have cleaned MAF and idle control and TB. Is it possible this is caused by a need for a tuneup . I plan on putting new wires and plugs in it this weekend.

I know this has been talked about many times but from first hand experience would you suggest double plats or regular plat plugs? Also advance has autolite professional 8mm plug wires. Any feedback on theses good or bad?
