I just had a few more question regarding things of possibility with this model of car. The following info I've taken from other sections of this site but was for different models of cars and I wanted to know if this was something that could be something to look into.
• Computer Controlled Engine Management System
• Catalytic Converter: "plugged" or restricted?
• Mass Air Flow Sensor. Heard somewhere this is only in the V6s, is that true?
• Fuel pressure regulator
• coolant temp sensor. How does this one relate to poor fuel economy?
• Spark plugs
These are all things mentioned for other models of cars and if anyone had any input on these regarding the Pontiac Grand Am that'd be greatly appreciated.
have the same problem?
