Why does my engine make a noise when my vehicle idles?
My equinox runs great except engine makes a strage noise when the vehicle idles at stoplights and such. At first we thought it was the air conditioning compressor which is giving trouble, but it does it when the air is off too.
Cette question est-elle utile ?
Would you describe the noise?
It is almost as if the driver is lightly mashing the gas with the vehicle in park only no one is mashing the gas and the vehicle is in drive with the driver's foot on the brake. It doesn't do it everytime, only randomly.
I took it to three different mechanics and they all told me something different. The first one said it was the air conditioner. He also put it on the comupter and didn't get any codes. The second one who is the air conditioner guy said it was the torque converter and sent me to a different guy. The third one somewhat agreed with the first one and said it was the air conditioner. What I don't understand is why it is fine in park and only does this when the truck is in drive and is worse when going in reverse. I tend to agree with the second guy that it sounds like something to do with the transmission. Since it is a cross over vehicle you can't check the transmission fluid to see if it is low. My question is, should transmission problems show up on the diagnostic computer?
I have a 2020 Chevy Equinox . Mine did the exact same thing. They changed out the turbo booster.
fixed it !
