All Mazda's turn on the check engine light at 80,000 miles to tell you that the o2 sensor needs to be replaced.
: How did they check your pistons?
: To check them you have to remove them.
: How did they check the wiring? Did the test every wire inside.
: What code is the computer giving out?
: simple replacing a bunch of parts is a waste.
: As for lubricating everything there isn't much to that. Make sure you have enough oil and transmission fluid.
: A simple test to do is to run the engine hear the rattle.
: Take the belt off and run it for a few seconds if the rattle isn't present than it is something attached to the engine. Water pump, alt, idler pulley, AC compressor, and whatever else.
: If the rattle is present it may be internal to the engine or transmission failing to disengage bad clutch/throwout bearing/pilot bushing. It could even be your starter staying kicked out.
: There are too many things to just guess at.
