93 - 5.0 Engine Miss/Flutter

I have a 1993 5.0 Automatic GT that has a miss/flutter when I drive up a grade with the engine under a load especially at low speeds (40-50mph). (I notice it especially in the overdrive setting on the transmission).

I have about 90,000 miles and did a tuneup about 10K miles ago (new plugs/wires, rotor, dist cap, etc.)

It is not a regular miss, but an intermittent miss.

Would a bad or dirty EGR valve cause this problem?

I just had the tranismission rebuilt recently (due to a total failure of the transmission) but the problem remains.

Any other ideas as to what may be causing the annoying engine flutter?

Unfortunately with something like this it could be many many different things. First thing I'd suggest is scanning the computer for codes. Hopefully it'll come up with a fault code which will point you in the right direction.
