I jump started the battery and accidentally reversed the

Customer Question

i jump started the battery and accidentally reversed the positive and negative leads. I corrected and was able to start the engine but it is now in fail safe or idle mode only. I believe I may have shorted something and may need a fuse or reset the ELectronic throttle. Which fuse(s) should I check and can this be reset?
JA: Most vehicles have two fuse panels. Have you located both?
Customer: Yes
JA: What is the model/year of your Lexus?
Customer: 2005 RX 330
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes. I have a flat tire in need of repair. I used a compressor to gain enough PSI to take to tire store when I then needed to jump the battery. I need to reset or replace fuse to get to tire store.
JA: Anything else you think the mechanic should know?
Customer: There was a spark when I reversed the jump cables that produced a little smoke on positive terminal. Car starts but won't get out of idle.
