I have recently been experiencing problems with my 95 Olds Cutlass Supreme. When I am driving on the highway and go around 50+ mph as soon as I stop accelerating and just try to keep spped my rpm drops and the car shakes slightly (runs rough) it goes away when I let of the gass, but as soon as I reaply the gas and go back to keeping spped it will do it again.

I have been told it was the tranny, but some people tell me it might be something with my fuel injectors or spark plugs. Not being a car person I have little clue.

Also wsometimes when I am at a stop or slow down and floor th3e gasss the rpm won't go much over 3 and won't pick up speed fast, than suddenly the rpm will jump above five and accelerate.

Would appriciate any help I can get.

My 94 Olds Cutless Supreme was doing about the samething, but it was getting about half the fuel mileage. My problem was a bad fuel injector.
