I blew my clutch and flywheel on my truck in January after 31,000 miles. (When I drive alone or without something in the load bed, I drive like I stole it.) That necessitated replacing both of those.

Last month, March, my truck had some problems related to firing the spark plugs. The engine would go haywire and the RPMs would spike all over the place. The shop said that the crank arm position sensor faulted, which meant the computer didn't know when to fire the cylinders. Quick electronics fix.

Last week, the exact same combustion problem surfaced. I took it back to the shop, and the same technician who fixed my truck in January and March spent all day Friday with it just diagnosing problems. Turns out he improperly installed the flywheel. Apparently it has a several magnets in it that need to be properly lined up when installed, and he didn't do that when he fixed it in January.

So, I don't have to pay for it. This all just goes to show that once you take something apart and start fiddling with the bits, it never gets put together back in the same way.
