Send the tcm to reprogramm or diagnostic. Tcm in the mazda 3 2.3l is over the gearbox under the battery. The excesive heat makes them malfunction. Or so they say. I moved mine to the firewall.

Quand je roule sur une route plate ma voiture roule très bien et Quand je prend une montée elle ralenti
This is a normal practice, the fact is that a car requires more resources for the engine when climbing a mountain and you need to press the gas harder.

CommentIdle problems with my Mazda 3
Mazda Mazda3 2011 Sedan 2.0 ALBA13 BL DRIVE L 55923 miles
The problem started when I had a mechanic clean my car's throttle body (it's a 2011 model with 90,000 km; I haven't driven it much). Since then, it has had idling issues. The engine suddenly revs up to 1,500 rpm and then drops back down. I’ve visited several mechanics; one suggested the neutral switch was the culprit (which makes sense, as pressing the clutch when it revs causes the acceleration to stop and the RPMs to return to normal levels). Another mechanic ran various tests on the throttle body—including a smoke test to check for leaks—and while the frequency has decreased, the issue still occurs about 10 times during a half-hour drive. What can I do? Thanks.

Jerking hard when taking off
Airbag warning light red
Mazda Mazda3 2004 1.6 petrol 96 miles
That warning light usually indicates a safety issue. I’ve had the airbag light on for a while; I took the car to the mechanic, and he fixed the steering wheel airbag's second stage, which was faulty. Now, after several months, the light has come back on. I’ve heard it could also be a problem with the seatbelts. If anyone has any information or knows anything about this, please don't hesitate to share. Thanks, everyone.
