92 ENGINE PROBLEM

1992 Buick Lesabre • 62,000 miles

Sometimes car runs smooth and sometimes it starts jumping and seems to have no power to go. Have replaced plugs and wires had a oil change. This car usually runs good for a few days then it starts jumping like it is running out of gas will not pick up speed.S weird for it to go from running good to running bad. Please help!

How long since you replaced the fuel filter and checked fuel pressure. With intermittent issues, you have to check when problem is ongoing.

Can you check for applicable mil codes? You should be able to check those codes, yourself.
