You must relearn the Electronic Throttle. Turn the key on for less than a second and leave the key off for 20 seconds. You're set.
changed battery in 2000 chrystler sebring and now will not idle
With my xg 300, the radio was turning on and off on it's own. I checked the battery and it was bad. Replaced it. Now it's fine again. Go to auto parts store and have your battery checked just in case. Could also be loose battery cables.
Change idle speed contol sensor Uncool the battery for five minutes to reset the computer.
clean the throttle body unhook both the batt. cables touch them together for 30 seconds hook batt back up and your good to go
Cleaning the battery terminals had nothing to do with the engine not idling properly. Just a coincidence.
I think your alternator doesn't work properly.
In the intake tube there should be a sensor (mass air )if you sparked that sensor it is now shorted and needs to be replaced
The idle is not adjustable. It is computer controlled with a idle air control motor that is on the back of the throttle body. If your idle speed is incorrect you either have a computer that has "forgot" how to idle or a sensor issue. You need to have it checked for codes, if no codes you need to reset the computer's memory. You can reset the memory by unhooking the battery for 5 minutes. If it now idles properly you should have the battery tested, a weak battery can cause the computer to "forget" how to idle.
If it isn't starting you have another problem.
Other than resetting the ECU, disconnecting the battery should not cause the bad idle. You have reset the ECU and it may need some time and driving cycles to idle correctly. But I am doubtful this is the problem. I would suspect this is just a coincidence, and you have another problem.
You need to enter the code into the radio.
You may have to clean throttle body if battery was disconnected for a while so pcm can relearn proper idle speed.
