My car hesitates when driving

Hi. Hope someone has some ideas as to what is wrong with my car. It drives fine for a while every day then out of the blue starts hesitating and sounding like it wants to shut off when we’re at a traffic light. It gets worse when I am making a turn, like it hesitates to pick up speed and starts like sputtering. When my car does this the muffler starts smoking really bad. The smoke is not a black color it is white. When it feels like it’s going to turn off, I have to put it in Neutral then it stops. They did say the fuel pump wasn’t bad so I am assuming spark plugs??? If anyone has any idea as to what may be causing this problem, I would really appreciate it. Thanks.

What year Acura Legend and approximately how many miles?

White smoke from tailpipe suggests water in the exhaust. Are you losing coolant?

@aricht41, thanks for the message, but please post replies here to help as many people as possible. I understand your car is a 1994 Acura Legend and has 110,000 miles on it.

This info will be helpful to those who have more knowledge than me.
