My car is experiencing a current drain , it idles lower than usual, when i rev the car it sounds fine but when i take my foot off the accelarator the idle drops down so low it cuts off the engoine; the alternator is charging , any ideas on what can be ca

I've changed the air flow sensor, TPS sensor, plugs, plugs wires, even the orignial coil pack. I have a MSD 430 blaster. The air idle control works.

Do a current draw test, place an Amp meter between battery pos and the cable, close doors and with key out read the current draw, if above around .15amps pull fuses one at a time to locate the circuit that is drawing current, also check for fusible links and test the alternator as well by disconnecting all plugs and main feed as a faulty diode in the rectifier can cause a back feed while still charging.
