Greetings! I have a beloved 2001 ES 300. Once while driving, I heard a loud popping noise like a small stone hitting the windshield. When I got home, I examined the windshield and found a small chip. Over the next few months while driving, I heard the noise again several times but found no new chips on the windshield. Then one day while *sitting still* in line in the bank drive through, I heard the exact same sound again! Has anyone else experienced a sound like this?

Thanks!

 

You might be having some slight backfire. When i run 110 race gas (great for cleaning your fuel system out) i get those popping sounds occasionally.

 

sean, where do you get 110 race gas? is your performance increased any?

 

you should watch out. it might be an evil gremlin taking apart your car.

 

LOL I hope you mean popping noises. Pooping noises would be quite offensive.

 

i can't believe i didn't notice that.

 

Eric, you can get 110, 111, and 108 octane at a few gas stations in my area. Usually it's available at 76/Gulf stations, Some Citgo's, and some marathon stations. Just call around and ask for "turbo Blue."

As far as a performance goes, the only difference race gas makes in a stock n/a engine is a smoother ride. It also cleans out your fuel system, which i will try to do once a year.

 

Ooooops.... (*bright red face*) Yes, I meant "popping."

Thanks for the responses!
