I have a 95 aurora. And lately when I am driving it it starts to buck and backfire when I get to about 45-55 mph. It sat for about 3 years. And it has 143000 miles on it. I just had the shift solenoids changed in it. I was going to change the plugs and wires but I had it put on a machine and it said it was the map sensor. So I changed it by the car is still doing it. Can some please help me with this.

Gotta start with tune up. Been sitting for 3 years, and has 100,000+ miles.

Anytime I've had a car bucking when accelerating, it usually came down to a problem with the torque converter not engaging properly.
Pay attention to the RPM when it occurs; I bet it always happens for you at the same RPM.
That's my two cent's worth,
Greg

The front transmission is shot and will cause a heavy jerk feeling when the TC is in full lock and you are going up and down hills. Anything more severe can be an engine lug, which can be a engine problem. Check the fuel pressure and replace the fuel filter most definitely. Old fuel and lots of dirt can be causing low pressure

Most likely an engine miss.....I see 10 engine misses for every transmission problem.
