Is the alternator charging properly?
how could i tell?
Is the battery light on in the instrument cluster?
the car starts but the malfunction liht comes on and says power is reduced. It sounds weird wile it idles.
Yes the engine power is reduced, how long was the battery dead?
1 night. I don't use the car that much and my kids were playing in it last night
drive about 15 miles per day.
How long was the battery dead for?
I let idle for about 5-10 minutes thinking the battery needed further charging but after 5 minutes its starts revving weird. sorry about the lack of tech knowledge - not a car guy
should i try and run it longer?
BTW - got a new battery a few years ago.
Ok I want you to try something, I will explain it now.
I would like you to hook up the battery charger, then insert the key and push the start button just until all of the instrument cluster lights come on, do not start the engine. Leave it like this for one minute and then turn it off and remove they key, wait another 3 minutes and then start the vehicle and let it idle for a few minutes. (Make sure all the doors are closed during this procedure) Then let me know what happens.
With the idle.
looks like everything is now normal. engine light is now gone with current idle. still hooked up to charger.
idle sound much better
Ok it lost it's initaliztion for the electronic throttle motor, but I also want you to fully charge the battery to make sure there are no further issues, and then you should be fine.
you are the man. I'll let it continue to charge. thank you.
sorry - I'm trying to figure out how I pay you.
