Question about 2004 Pontiac Grand Prix
I was at a stop light when the car began to idle up and down and seem like it was going to stall out. Then the electronic systems failure showed up on the information center. When I shut the heater off it went out and the car ran fine. Is this a battery problem?
I have had the same warning...charging system failure. So far I've tried 2 different altenator's...2 used batteries and ended up buying a new battery. Problem still exists to the extent that when i often shut the car off and go to start again..Nothing. I disconnect the negative post i hear a clicking sound and hook the cable back up and try turning the car over ...it starts without needing a boost...sounds like it resets and then allows the car to start. I've taken it to a number of mechanics and they have no clue...any idea's ?

IT COULD BE THE BATTERY BUT I WOULD LOOK TO THE ALTERNATOR TO MAY HAVE WARN BRUSHES

if you know where the EGR valve is located take a wrench and gently tap on the valve if you notice an immediate change in the idle you have found the problem, the problem is the egr vlve is slightly binding and the right way to fix it is to replace it

fuel pump is burned out from running out of gas, the pump is cooled by the gas it sits in inside the fuel tank, when you run low on fuel or out of gas you over heat the pump severely and the bearings in the pump seize up, have seen it dozens of times in my 30 years of dealer work.
