I have a 1994 Pontiac Grand Am with a 3.1 engine. A scan tool test shows 2 bad Quad Drivers. A new computer is in its future I guess. Both online & locally the computers listed state that "Flashing" required before install. Where does that get done? Dealership? And does anyone have an idea of the cost? Thanks, Mike
My '95 has given this code for years. It runs flawlessly, gets good mileage and passes emissions. If yours runs ok, don't worry about it. What scan tool are you using?
On a 94? None of the quad drivers control the ignition coils.
