[Missvzhsvclubby]

Hi everyone bit of a weird one but have a noise when I take my foot off the accelerator it’s like a chirping or cricket noise?
It’s extremely annoying
Stops when I brake doesn’t do it when accelerating only when I take my foot off??
Any help would be great
It’s driving me insane…
(Have changed pulleys belts my brakes and rotors just been done aswell)

Worn pulley tensioner? (Either of them)
Vacuum leak? Smoke test to confirm.

Have changed all pulleys and even changed the belts as that was first thought…
I’ll have to check vacuum leak didn’t think of that

You changed the pulleys. Yes. I’m talking about the tensioners that two of the pulleys are bolted to.

Do a smoke test to find a leak on the intake side.
Do one on the exhaust to see if there might be a cracked header or similar.
