Yesterday, I drove 30 miles on highways, then parked the car for about 10 minutes when I got into the city. When I started it again, it sounded as if there was another motor running alongside the engine. At first, I thought someone had started their car near mine, but when I opened the door, the noise was coming from my car. It sounded like the engine was idling way too fast.



Then I started smelling something burning.



I turned the engine off, and I heard the normal sound of it going off as it should. However, this other sound--what I'd thought was someone else's motor--kept running. I opened the hood to see what was happening, and some smoke was coming out of the engine. The smoke was coming out the right side of the large plastic cover on the main part of the motor. I really thought the car was going to catch on fire.



After a few minutes, it finally did stop, though it smelled like burning rubber, and it was still smoking for a little while.



I called AAA, and they towed my car to a mechanic. He thought it was something electrical, so he ran some tests, all of which came out OK. He started the car, took it for a drive, and it's behaving perfectly...so far. He's going to run more tests, but right now, he's baffled, because he can't recreate what happened to me.



Someone else I talked to mentioned that this might have something to do with the throttle, and I mentioned that to him.



The only things I've been doing differently of late are that I have been using the cruise control, and I have forgotten to put any sort of engine cleaner into the gas tank for several months now.



Anybody have any idea what this might be? If you have any follow-up questions, please ask, and I'll answer them to the best of my ability.



Thanks!

This post is WAYYY overdue, but if anybody should happen to be searching for a solution to a similar problem with their car, I thought I should post an update, anyway.

Turns out the starter needed to be replaced.
