Just received this printout from Mazda dealer.
Looks like alot of gobbly-gook to me except for the bottom part.
The read-out recorded my last driving session and shows some misfiring.
Looks like it may be my cat?
I've had the vacum testing done, de-carb procedure and all plugs/coils and wires replaced with the BHR ignition set.
Still having some hesitation and bogging at the high rpm's with no cel's.
Hesitation only happens after I have been driving for awhile (close to or more than an hour)

 

Engine is bad.

 

Oh, forgot to mention; had the compression check done and results came back as normal readings to higher than normal compression.
Engine has 99,000 klm on her.

 

if the compression test came back normal, and you changed the plugs and coils. I would say that the CAT's efficiency is probably below the threshold, or maybe try looking at the o2sensors, and visually inspect the cat core and see if its broken or damaged at all. other than that i have no idea. good luck

 

Those are very small #'s of misfires.....likely negligible

I would check your fuel pump.....

Bad gas?

 

Open up your glove box and see if there's a can of liquid schwartz in there.

 

alas the schwartz is not with me
Could the cat be clogged and not giving off any cel's?

 

Cat could be clogged. Take the midpipe off and physically look through it.

 

The response I received from Mazda Canada today was the cat is fine.
The only other thing to check now would be the SSV?
However I am not receiving any cel's (specifically a 2070 code).
Is it possible to have a sticky SSV and not receive any cel?

 

From the printout, the cat is fine, as well as the 02 sensors. 4 misfires over 10 drive cycles is nothing.

I would check your fuel pump as well.
