I have a 2001 Toyota 4runner and about a week ago my daughter said the powered steering wasn't working. 2 of the belts had come off so I replaced all 3 belts. when I was driving home, I found out my brake lights were not working. The regular lights worked fine. I checked the bulbs and they were good. I then proceeded to check the fuses and they were good. I then replaced the brake light switch. Now my brake lights are not working and my engine will idle only. If I try to give it gas it just sputters and eventually dies. I'm at a loss as to what else could be going on. Any ideas on what could be going on?
