Sputtering a little…. 45-60MPH
94 Bonneville SE 150,000miles
When im going about 45-60MPH and the tork converter locks and give it a little more gas to get up a hill it sputters a little like its misfiring or the timing changed.
I just got the car last week and I think the plugs and wires are the original ones on the car.
Im thinking maybe that’* the problem or maybe a throttle position sensor.
Any ideas on what might be the problem???..

Once the torque converter locks you will feel any ignition problems that exist.
if the plugs and wires are on your list of items..change them and go from there.

and it might be your spark plugs
one way to find out is at night when there is a little bit of light left take your car open the hood (while engine is running) take a pair of heat gloves and put them on and then one buy on remove each spark plug carefully make sure though that you keep in close enough that it makes purple or electric current
for your fuel injectors( that is probablly your most likely fix) take out the fuel injector rack and find out if there is any bad ones and if there is replace them and put the rack back on
do try these and tell me what happens

bandit...do the easy stuff first. 90% of the time, what you're experiencing is ignition related. If that doesn't work, we'll address other things. For now, pick up a nice set of plugs and wires. Preferably AC Delco.

Lucas: he does not mention injectors in his post. The injectors are most likely fine and do not need to be removed. If anything a bottle of injector cleaner run through the fuel system when changing the plugs and wires would be a good idea.

I learned then that later cars had the 4T65E instead of 4T60 and those torque converters didn't lockup 100%. Instead they had a slip factor that is variable so that you don't feel the motor'* vibrations and don't feel the engagements.

If his car has 150,000 on it and it looks like the plugs and wires are original, he can't go wrong replacing them first. They NEED it! Just make sure to use good plugs and wires.
Before trying to get into a problem diagnosis, it'* always good to review the tune up status of your car. Never underestimate the value of a good thorough tune up. Like it says in the tech section.
The very least you will accomplish will be to eliminate those items as sources of any problem.

Welcome. Loving the weather here in rochester as well. i would also suggest checking/changing the Plugs and wires first.
After that, if it doesn't change we can start looking at other things.
Where abouts are you in Rochester? There are several members from this area, myself being one of them. I live in the Cobb'* Hill neighborhood of the city, just off Monroe ave. Another member Rob live on RIT'* campus. Both of us have a decent amount of knowledge and I also have the 1993 Service manuals here that might help us diagnose it further (L27 should be the same/similar enough for 93/94) I will be out of town this weekend, but would be willing to help in the evenings this coming week. Let me know.
