They are super nice folks and I'm not claiming that I was ripped off. However, outcomes are outcomes and my outcome was changing my own ignition coil in the Napa Autoparts parking lot after spending $1,200+ on a new mass air flow sensor, air filter cleaning, and spark plug re-torque at Pacific Motor Service. While I'm glad I now have a clean filter and a new MAF sensor, those weren't the issues that caused the misfire and subsequent check engine light. After I brought it back when it threw another check engine light the same day I picked it up the first time, they did another diagnostic (that I wished they had done the first time and saved me $1,000) and discovered that it was an ignition coil. They get two stars because they didn't charge me for the second diagnostic but they also didn't offer to make anything right and pre-emptively argued that they were correct in doing the initial $1,200 in work. They also said they wouldn't want to just replace the one ignition coil and recommended I do it myself. I left the shop with the same check engine light that brought me there after two trips to the shop and out $1,200+. The car ran great after I installed the ignition coil at Napa's parking lot. Would not recommend Pacific Motor Service.
