Chugging uphill

Chugging uphill
My '97 LSS (88) begins to chug when it's climbing an uphill grade. Runs great on the flats, but sputters on any type of uphill grade. I've already changed plugs, wires, air and fuel filters... any other ideas?
The car has 3.8 V-6 (non supercharged) 105, 000 miles and could it be time for new injectors or coil packs? Help please, thanks!

I found a slight up grade yesterday and the car did downshift okay with no hesitation. The problem seems to develop on longer hill climbs. Does anyone know what the duty cycle of the fuel injectors are? Had them removed and cleaned once and usually run some fuel treatment when I change the oil. Trans has been serviced too... fluid and filter.

I'm going to second the coil pack or ignition module. I've had a couple of cars now that have exhibited this behavior. It feels like the TCC is locking and unlocking, but in reality it's a misfire that is magnified by the fact that the TCC is locked up. In both cases it ended up being ignition that was causing the problem.
