Welcome Aboard!Started with problems pulled my oil dipstick out after strange oil leakage.
It sucked air in and variable engine speeds. Diafragma sucked down.
Lucky I had already seen CruzeKits.com and even got a email conversation with the owner.
I was warned in advance.... my dealership had no time for a diagnosis so watched some diagnosis videos it's easy to find out without a schooled mechanic.
I rest my case 😌
Glad I found this solution forum
