2.5l tbi distributor question

I have an 89 with a2.5 FBI that sputters at around 200 to 2200rpms in any gear. If I step on it, of is smooth. At idol, it's smooth, but every now and then, it'll sputter slightly. I've replaced the fuel filter, changed the plugs, gapped at .35, changed the plug wires, cleaned the Carb, seafoamed it. I noticed the distributor cap was loose, so I pulled it, used Scotch brite on the contacts and tightened it all up. Any ideas of what else could cause this?

I have access to my brothers wrecked 91yj (I think he's regretting storing it here) and was thinking of pulling his distributor off of it to put on mine. But it's an mpi 2.5. Will it be a direct swap? Will it even work? I've searched here and Google, but wasn't able to find an answer. I'm starting to think there's a reason I didn't find an answer. I'd someone could clarify or fill me in on what would need to happen for it to work, it'd be greatly appreciated.

The part numbers do not cross, I think it more of and electrical issue, than a mechanical one. Have you done a compression test? Sounds like that might be the issue, how many miles on the jeep? Also, just because I've seen it done more then once, the fuel filter is facing w/ the arrow pointing towards the engine correct?

So, no go on the distributor, huh? I haven't done a compression test on it, but can. The odometer reads 162,000 bit I'm running 33's with no correcting gear, so it's probably more towards 200,000. As for the filter, I know I made sure the arrow was facing the correct direction, bit I'll check again to make sure tomorrow.

Yeap, no go, mechanically I think it would drop right in..But the you'd have to go hacking the electrical side of it and your bro prolly wouldn't find that very amusing..haha, Yes, do a compression test and lemme know what you come up with.
