Just replaced the throttle body. When I accelerate, I hear a rush of air coming from the right side of the engine. It doesn't do it when cruising at a set speed. Cars idle is slightly off as well, but no relearn was done with battery after replacing throttle body. The vacuum line appears to be fine as well. When the throttle body was replaced, the mechanic said it had more oil in it than it should have. My Eco boost also has not worked in months, but I did not care for it anyway so as long as it wasn't a problem, I let it be. The air rushing sound seems to be worse between 40 and 45 MPH. My brakes are fine as well, no change in them, and I have no codes either.

Hi,

Is the check engine light staying on when the engine is running? As far as the noise is concerned, when you are accelerating, the throttle plate opens, and a lot of air enters the engine via the throttle body.

Also, the charge air tube for the turbo may be leaking. That would explain why it isn't working.

Do me a favor. If you look at the attached pic below, I circled three things. Number 1 (circled in blue) is the charge air tube for the turbo. Do the best you can to see if anything is cracked, damaged, or disconnected.

Numbers 2 and 3 (circled in red and black) are the air tubes from the air filter. Make sure they weren't left disconnected.

If possible, have a helper throttle the vehicle on and off quickly while you listen to the engine with the hood open. See if you hear the sound.

Let me know.

Take care,

Joe

Hi Joe, no there are no lights or codes, which is why I was thinking that something may not have been put on tight enough as well. Thank you for your response! I will definitely check out the things you circled in the diagram.

I tried what you suggested and found nothing loose or cracked. The helper I had noticed vacuum when taking oil filler cap off, so he suggested a manifold gasket? Does this sound plausible?

Jessica,

When you say a vacuum, that shouldn't be and wouldn't be a manifold gasket. Is it possible for you to record the sound and upload it for me to hear?

Let me know.

Joe

I can try to record it and he just put his hand over where you fill the oil up with the cap off and car running and said it had too much suction. I read that some suction is normal though.
