Hello, welcome. My name is Mike, I will do my very best to
assist you with your question.

Has any of the shops performed a compression test and a cylinder leak down test?
Customer: replied 3 years ago.

yes conpression tested ok.

The vehicle needs to have a cylinder leak down test performed which is different than a compression test. The issue that you are having is consistent with a valve,valve seat,leaking down which will result in your issue. This can happen even at low miles .
