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.

Why does the 2001 Hyundai xg300 radio wipers and hazards turn on and off by themselves?

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.

How do you adjust the idle on a 1998 Dodge Ram 1500?

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.

1992 MGMdisconnected -battery post then reconnected will not idle now?

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.
