Engine Mechanical problem
1993 Oldsmobile Delta 88 6 cyl Front Wheel Drive Automatic 240000 miles
I have a delta 88 1993, 240000 km when I pick up speed to 60 it starts tugging.I also noticed sparks from the engine closer to the windshield. My father had the module replaced new wires and plugs. It was tested and nothing came back. My waterpump went so I replaced it and I changed oil and antifreeze. Ive had it to numerous pple and they said module if not that plugs and wires. Like I said there all new. Do you no what the problem could be?
