93 with 3.8 engine missing problem

[govols100]

Just about anytime theres the least bit of strain on the engine it develops an irregular intermittent miss, or starts shaking at least. Pretty sure its a miss though. It does it most when I'm driving at highway speeds and come to a hill and I either hit the gas to try to maintain speed or the cruise control hits the gas to try to keep it going at the set speed. Otherwise the car starts fine, idles pretty smooth, transmission shifts smoothly in every gear, etc. It has had a complete tune up within the last week and that didn't help. Also took it and had the injectors cleaned. The only thing I know to do is take it to the dealer and let them put it on the computer. Any suggestions? I'm totally baffled!!
