Engine Performance problem
2003 Buick Regal 6 cyl Front Wheel Drive Automatic 123, 00 miles
The car recently has had a fuel filter, spark plug, wires and one coil pack replaced due to a code which shows a misfire on no.1 spark plug. The poor acceleration symptom went away and now it's back. It feels like the motor its starving for fuel and I have to depress the accelerator way down to the floor to achieve the desired speed. I purchased a fuel pressure regulator and I am about to instal it, but how do I know its not the fuel pressure regulator and its something else. Without a code, I don't want to chase a problem that does not exist.
have the same problem?
