Will a faulty oxygen sensor cause a car to jump and cut out at around 70
mph? Or is it the lean burn system failing?
The car has a 318 and an automatic tranny. I have replaced the plugs, wires, cap, rotor, alt., coil, and other items that needed to be replaced. After doing all this work, the problem got worse and not better. It cuts out atleast every mile while driving long distances and drastically reduces gas mileage.
It purrs like a kitten all of the time it does not cut out.
