This is my 1st post so I hope it's in the correct section.
Just after some advice really before I take my Astra M4 1.4L (16v) into a garage.
I am useless when it comes to cars but can take things apart very easily. It's just putting them all back together
I am trying to work out what the blowing/farting sound is that comes from the front of the car when I change down into 3rd from 4th. There is a bit of a slow pick up / power loss and I can put my foot right down and the car takes time to respond pick back up.) When this strain is there, there is a farting noise that comes from the front of the car until the car has picked up speed again then it goes.
This seems to be getting worse but everything is silent when idle or revving the engine.
For example if I dropped down into 3rd from 4th to take a right and I' crawling to approx 5 mph then put my foot right down to get the power to speed back up the car makes a blowing/farting noise from the front until car picks back up. The noise is quite loud if I have the window down.
Can anyone help??
Thanks in advance everyone
UPDATE - I have just been out to look at the air filter and have noticed that one of the pipes looks a little loose. See image -
Where the blue ring there is nothing secured into this hole. The entire pipe that's connect here seems to be just slipped over top.
Still I'm a novice but could this be the issue here...??
