Exclamation battery Draining

I have a 97 camaro standard model, I am having the battery drained. The alternator and batter have been replaced, even with the new ones it will still happen, just not as often as with the previous parts. It normally happens when I am at a stoplight idleing, it causes my car to shake pretty severely sometimes and die. As soon as I hit the accelorator it will come out of it if i can get it before it dies. It was taken to a dealer to see what the codes read and it said multicylinder missfire,so I replaced replaced the spark plugs, spark plug wires and coils. It's only improved slightly but I am still having the same probelm. Anyone have any ideas where to start looking?

Re: battery Draining

Well, maybe I'm not familiar enough with late model computer controlled engines, but I'd ask how the battery is involved with missing and stalling at idle.

The battery is used to start the engine. Once started, the engine runs off the alternator, and the alt charges the battery. Therefore, if the battery consistently starts the car, its not a battery drain problem.

Since the alt typically produces less voltage at idle, you may have a problem with grounds or connections to the various electrical items involved with running the engine, such as the computer. The computers hate bad connections, low voltage, etc.

Get a decent DVM and check the battery voltage with the engine off, and engine running. 12.6VDC off and at least a few Volts higher running. The Voltage should go even higher as RPM increases.

From here it gets into troubleshooting the electronics and sensors, which can be fun.
