Ok...get ready this is going to be a lengthy post so
I can try and cover all questions up front.

1995 Trooper 3.2 SOHC Auto 165,000 miles
4-5 inch, 34 inch tires, 4.77 gears
engine stock except K&N box filter which as
been there 40,000 miles (yes been cleaned)

Currently the truck is having a real tough time running under 2,000 rpm at idle it is the worst. Once this truck gets approaches 2,000 rpm the frequency decreases to a point either it stops happening or I don't notice->(not likely). This is the second time it has been like this in the last 3 months. It is constantly missing and stumbling, like 2 or 3 times a second. It appears to only miss every few seconds when I first start it, and continues to get worse as the truck reaches full operating temp. It has been going on at this rate for about 5,000 miles.

For those that have the oil in plug well situation it acts very much like that (mine had that issue-previously Fixed) So when this started first thing I did was check all plugs and wires. Didn't see a problem, however still replaced plugs and wires just in case I had a bad one that wasn't obvious. This didn't help. So I replaced fuel filter...nope.

Then I replaced all coil packs and it solved the problem for about 5,000 miles. Now it has returned again. Is it really possible that the new coil pack have gone bad in less than 2 month & 5,000 miles? Sounds to me like there is a larger underlying issue, that the new coils packs were able to hide for a short period of time.

Ok guys ask more questions and lets get to the bottom of this.

Thanks In Advance
