Turns out the cause was a failing battery, not anything to do with the engine.
Actually the battery plays a very important part in the operation of the engine, and the transmission, the brakes, every system in the car that uses electricity.
A fully charged battery in top operating condition is integral to a properly functioning vehicle.

All too often these days mechanics simply throw parts at a car until they throw the one that replaces the malfunctioning part. It is too difficult to actually learn troubleshooting and follow a logical series of steps to track down the problem.
Originally posted by tim60 Of course, the customer pays for both the real repair and all the wrong turns along the way.
I haven’t paid someone else to work on my vehicles in over 45 years.
As I’ve said before, I became a mechanic because I didn’t like paying some moron to make things worse.
That said, there are actually more good mechanics than bad ones. It’s just the few who give the rest a bad name.
