Question about 1998 Pontiac Grand Prix
Did he weld it? If so, did he disconnect the battery?
I had a 1990 Cadilac Devile that jerked around 35 mph and it was missing on a cylinder because the fuel injector was not firing.
I wonder if this is happening to yours.
The solution, in my case, was another ecm because the old ecm was not firing the fuel injector.
You can check this by using a fuel injector tester that lights up or by listening to the fuel injectors click with a stethoscope.
