I have a vehicle with a cylinder misfiring (according to my OBD-II code reader). I have decided to have a mechanic repair it, as I have never performed a similar motor vehicle repair.
Note that the only consistent symptom besides throwing the cylinder misfire OBD-II code is a little accelerator hesitation.
Not consistent was also some really bad (perhaps metal on metal - hard to tell) grinding sound for about 10-20 seconds when first driving after not using the vehicle for over 2 months. It sounded real bad, but resolved on its own before I could even turn around and park.
To help me evaluate different mechanics, I would like to know what is likely required to properly diagnose and repair this problem. With the knowledge you provide, I will hopefully be able to filter out the scammers and find a trustworthy mechanic for this job.
