Check the crankshaft positioning sensor..it will cause it to run bad and to die out..it malfunctions and causes the other parts associated with it to malfunction as well. I e. Air conditioning, throttle positioning sensor,egr valve, smog pump pcv valve. As for the battery draining issue..did you do a parasite elimination test? Simply explained by removing ground wire from battery. Hook a multi meter in series with the grind wire. Place the meter on the windshield so you can see it from inside the car. Remove one fuse at a time from the box checking the reading on the multimeter..when the right fuse is removed the parasitic drain will drop to around 0.05 volts drain..this is acceptable..repair the circuit and/or repair the draining component. As needed..
