The service writer just called to ask why I felt the need to do a compression test. The tell tale sign for me was the engine skipping a beat on start up, not to mention the extreme hesitation. I'm not sure why the service department would need to know why I decided to check the problem myself. I am hopeful that they are just exploring every condition and cause and not looking to screw someone for the diagnostic fee. I felt like saying "would you ask me why I decided to check the air pressure in my tires if I told you my tire was flat?" I didn't say it. I will say however, that so far I am pleased with the attention the service writer is giving to me. I sure hope it continues so I can become a "Raving Fan" and give the dealership/service writer a great review. I am keeping the faith, for now!
