Hey guys, I was driving my car today and everything was fine and normal. I was picking up someone and when I got there, I had turned off my car for about 30 seconds. When I started the car back up, it wouldn't start. So I tried it again and it came on, but had a really rough idle and wanted to shut off from a lack of power or something. While it was running, there was a very loud clanking noise, like something was loose. That sound was very loud and apparent, so I couldn't tell exactly where it was coming from around the engine. I NEED HELP! I use this car for my job. I'm low on funds, but I obviously have to get it fixed, or I'll lose my job.
