I have a 1989 Plymouth horizon. The problem I’m having is when you give it gas and it starts to come to an idle it dies. But it can be saved if you feather the gas until it idles normally again. It has a brand new fuel pump and fuel filter, along with spark plugs and spark wires.

Clean the throttle body, then check to make sure the idle air controller is clean and has full travel to the open position. (Take off the idle air controller, check for free movement, and give it a good visual inspection to make sure it is clean. It may need a shot of carb cleaner on the moving surfaces.)

That’s a symptom of a faulty idle air control valve.
