Does it act like it has a rpm limiter such as not wanting to go above 2500 rpm? Thanks.

Is check engine light on?

Customer reply replied 4 months ago
No engine light at all
Mazda Mechanic: Dan, Technician replied 4 months ago

To me it sounds like you may have a clogged catalytic converter. A simple test is to remove the front oxygen sensor completely from exhaust and see if that helps bring power back, if so it is clogged. A clogged converter is common to cause this symptom without turning on the check engine light. Let me know if you have more questions, thanks.

3rd time I heard this, I will relay to mechanic tomorrow. Thank you. One more thing, if he removes the oxygen sensor he has to drive with it off to see if problem still happens?
Mazda Mechanic: Dan, Technician replied 4 months ago

Yes you will need to drive with oxygen sensor removed otherwise you can install a pressure gauge in oxygen sensor hole. Pressure should not go over a few psi while reving engine. Let me know if you have more questions, thanks.
