Why is my1995 Buick Park Avenue is coughing and sputtering while driving?

What is your question?

I have replaced the MAF, fuel filter, fuel pressure regulator and the coolant temperature sensor. I have to use the 2-foot method to drive it down the road. The car will not stay idling. Check engine light comes on after a few seconds. No noises or leaks. Fuel pump checks out good. Maybe the fuel sensor?

What makes this problem better or worse?

nothing
