Yea my favorite is that they will do a recall to put some foam around the gas tank so it stops making noise but they don't bother at all to address the broken clutch pedal situation.
If their sales were as high as Toyota's was i'd make a big deal out of it and go to the press. But I like Mazda they are the underdog! they throw a bunch of ford parts assembled in mexico in their Japanese cars.
Its just great.

Yea I'm pretty sure mine is compression as it didn't pick up on it until the compression test. I've replaced fixed and inspected all systems that are called for in the fsm to no avail. My numbers weren't to low but low enough for a rebuild.
Carlos get the compression test and lets see the numbers. depending on cranking speed anything 7.0 and lower is on its way out.
the FSM mentions nothing about the 02 sensor being at fault for misfire codes.
But ya never know.

is there any new news on this? Im experiencing the same problem but the flashing light only comes when I'm punchingmit. I am FI which I know contributes to the issues but just curious as to the compression test results.

It ended up being a couple things, I had to reset the crank sensor after replacing it, set of new coils went bad so had to replace them n the aftermarket wires didn't make the coils any happier, lol so basically the major thing was the coils n then wires the crank sensor had been reset from the beginning.

Power!!
imagine that. It's the same fix to the same problem that everyone has. Crank angle sensor, coils, plugs, wires are the most common problems with the most common solution.

my ****** engine light coming back on P0302 AAGAAIN! i thought it was gone for good. its when i hit 5000rpm it comes on flashing then shots off, and the 3rd time it flashes the stays on solid. New coils, new spark plugs (Done before misfire) dont know what else it could be... wires? some sort of sensor? they said they did all the resets including the KAN reset.

So I should do the same i guess so i should check this stuff out and tell them to check it?:
1) Crank Angle Sensor
2) Carbon Clean-up
3) Check spark plugs that were replaced few months before misfire
4) Check wires
5) Injectors
???

ok so i had the same problem and changing the coils solved it but it has only be a couple days so we will see. you spoke about the crank sensor. how do you check this and fix it if it is a problem?
