Question about Chevrolet Silverado 1500
It sounds just like a vacuum leak. If you checked all lines and hoses it may well be a intake gasket leak or cracked intake.
Usually a leak like this will give you a Trouble Code and the Check Engine Light comes on. If so, drive vehicle to an AutoZone or Checkers for a free scan of the codes, that will help to pinpoint the problem.
