95 3.2L missing on downward rpms

I have a 95 3.2L. I noticed a couple weeks ago that when you slow down and the rpms drop down to around 1000 rpms the engine starts missing. I replaced plugs and wires and it still does it.Before I changed plugs and wires it would miss some to thru the driving range when going up a hill or upgrade.It doesn't do that anymore, but misses around 1000rpms.Any ideas? :screwy:

I have a 95 3.2L and at idle is has ALWAYS sounded like it misses once and a while. Kind of pops and stuff while at idle. Dealer checked it numerous times and found nothing wrong. Truck runs fine, that is just one of its quirks I guess. Maybe yours is same....
