Any help would be greatly appreciated!!! Recently I have had the front left and right CV axles and control arms replaced due to me hitting a curb. I have a 05 es 330 V6. After repairs I went to start to start the car and it idles very low at start up. My check engine light is on but I haven't got it tested and my brakes are too bad to drive to get codes ran currently. I did accidentally leave the keys in the ignition overnight and killed the battery. 1. What could be making it idle low.

Hello,

I don't think that CV axles and control arms is what caused your idle to drop. Unfortunately, there can be a dozen of different issues that can cause the idle to drop or to be unstable, from some sensor to a vacuum leak. You will have to read the code in order to diagnose the issue.

At some car parts stores you can actually rent a scan tool - you pay its full price, then get the tool for as long as you need it, and after you are done, you just return it for a full refund. That is how you can scan codes without driving your car there.

P.S. I would also check if everything is connected, and all the fuses are good. I've got a CEL and dead overdrive today, and it turned out that I forgot to reconnect my Throttle Position Sensor, which was fun..

Hope this helps and best of luck!

Additionally, since the battery was discharged the idle speed may correct itself after an idle relearn. If needed, search CL for more info on the topic.

CEL could be from a damaged ABS sensor taken out from the collision.
