So my next concern would be a plugged fuel filter starving the motor for fuel not allowing it to take in more fuel as you press down the gas peddle.
When is the last time you replaced the filter?
I bought the car two weeks ago so I dont know when the filter is changed. Where the filter is located?
Limp mode? When it came to Bonnevilles?
Could it be related to the fact that my friend drove the car and changed the gear to the 1st gear while driving. I dont know how fast he was going and I dont know what was going through his mind when he did it... But I think after that the problem started.
Could the PCM be reseted easily? Because the service light is on once in a while as well.
