My forester started sneezing a month ago. (a loud 1/4 second blast of compressed air sound) This repeated at 36 second intervals at highway speeds. It doesn’t sneeze at idle and I don’t want to put my head under the hood at highway speeds. Occasionally I have gotten a 2 second blast. Any ideas?

ok ive had my giggle for the day.

It has an allergy?

How many miles, stick or automatic, does it do it after its warmed up or all the time, any particular engine rpm?

Is it running a fever :)

From the engine compartment, probably on the driver’s side, a sound of blasting air for a short interval that seems to affect the engine power in a small way. It may only happen when it is warmed up.

120,000 miles, Automatic, I think it needs to be warmed up. It happens regularly at highway speeds. I tried to load the engine by setting the brake putting it in drive with the AC on in my driveway but it wouldn't sneeze. I'll try running the engine at 3000RPM in park and see if it sneezes.
Thanks for your interest

hrmm i have to think about this. I had a ford do this once, it was an old escort, it was blowing off refrigernat for some strange reason.
I doubt this is the problem. Is it a cough or a sneeze?

This sneeze did happen at idle a few seconds after I started it but not at idle after it warmed up. It will sneeze at 30 - 40 second intervals at highway speeds. It is comming from the driver's side of the engine. I hope this helps.

Have a look for lose/leaking hoses and such around the brake booster.

lets start with basics How many miles, auto or stick. Has the car had a timing belt done. Usually a cough can be a backfire through the intake, an exhauust leak, a valve timing issue.
Go to an autozone and have them check for any codes.
Does the car loose power during a sneeze?

is it more like a "CHHOOOoooo" or more like a "PPSSSTtttt" or more like a "FFSSSShhhhh"......i know this reads funny, but there's a difference.

Thanks Nipper!!!!!
You asked about the warm / cold function. This helped me to explore the start sequence and the various cycles the engine goes through. It would sneeze 2 seconds after a cold start. Late one night I started the car and hurried to stick my head under the hood and saw sparks flash from the AC clutch. When warm (at idle ) the noise noes not happen, but can be heard at highway speeds ( high RPM ). I had been feeling a momentary loss of power durring the sneeze at highway speeds when the clutch engages ( added load ). This is seams to maks sense.
Thank you all for your input to this forum,
jtarne
