Something causes a slow drain on your battery. As it does, your battery slowly discharges. If you know that your car will be not used for several months, you might try disconnecting on of the battery terminals.
Sounds like to low an idle speed.
No, that has nothing to do with idle speed.
Not likely but possible.
the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved. the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved.
if battery has gone dead or has been disconected you will have to have your idle relearned How do you relearn the idle?
Hard to say as it depends on the battery and how good it is. A good battery can sit for 6 months and easily still start a car and 1 year is not out of the question.
Cleaning the battery terminals had nothing to do with the engine not idling properly. Just a coincidence.
No, that will have no effect on the battery.
If, by chance, you let your car's battery die entirely, I have heard of occasions where your car's computer becomes disorientated, or reset if you will, and your idle can get messed up. what i would do is avoid letting the idle drift too far below 750 RPMs and your computer will eventually re-learn what your proper idle is over time.
I would assume this is a Stratus, and that the battery had been disconnected during water pump replacement. 1. Disconnect the battery again for 30 seconds. 2. Reconnect battery. 3. Turn key to "run" position, (not start), for 5 seconds. 4. Start car. 5.. Idle relearn should be complete.
No, but a bad alternator will.
No. Just reconnect the battery and let the car idle for 5-10 minutes and then start driving the car. The car will relearn your driving habits after a week or two. . . .
