Hello to everyone! I am getting ready to buy a 1982 Mercury Grand Marquis 5.0L with carb and I would greatly appreciate some help. I am generally aware that the car has a computer (EEC) that controls basic engine functions. It is my understanding that the EEC receives input from things like a crankshaft position sensor, O2 sensor, throttle position sensor, etc. It then uses all of the collected data to adjust things like air/fuel mixture, timing, etc.
1) Can the control of these basic engine functions be removed from the computer (EEC) and returned to the driver? That is to say, can the variable venturi (vv) carb be replaced with one that is manually adjusted? Also, can the distributor be replaced with one that is manually rotated to adjust engine timing? I would love to take the computer completely out of the loop.
2) Since the car is now 26 years old, would performing #1 create any problems with yearly safety or emission inspections? I heard something about the Federal Clean Air Act of 1990 but I didn't understand it. Does a car this old actually have emission standards and requirements?
Can someone please help?
Thank you!
