2006 Scion tC noise when accelerating

All of a sudden I have a sound of marbles in a tin can when I accelerate or put the car in gear. It does not make this sound in park or neutral.


#2

Is the check engine light on? How many miles on the car? Have you changed the brand of gas you buy lately?


#3

The check engine light is not on. I have 60,000 miles, car is used only a few times a week the go 60 miles of highway driving. Yes I just bought gas from a station I never used because I was running low on fuel.

I’d say based on that, you got a tank of bad gasoline. What you may be hearing is detonation caused by the poor fuel. As soon as you make a little room in the gas tank, I’d put in some premium fuel to add a little octane. Do that until the noise goes away.
