Need Car Maintenance Advice

[Jodi1980]

After my 1994 Honda Accord drives for about an hour with the air conditioner on high, it will start to make a 'racing' sound while in park. Then when I put the car in drive, I don't even have to put my foot on the gas and the car will go at about 30-40 miles per hour by itself! I shut the air off and the car went back to normal. I just got a tune-up. Has this ever happened to anyone??

Hasn't happened to me, but I recommend taking it back where you had the tune up done.

Your throttle could be sticking. I'd go get it checked out my a mechanic right away. That's not good.
