For some time now i felt some sluggishness while driving in the city, i have tried to reset the automatic shifting a few times but no relief...
Its annoying that i need to floor the pedal to activate kickdown but because no check engine light my local Mazda dealer could not do much... and i tried to ignore the problem as long as possible.
last Sunday i went on a long trip 150km +/- important to note i went from 2.300m to a place 125m above sealevel and returned to 2.300m sealevel.
That day was around 30 degrees Celcius or 86F°
about halfway back i started smelling a strong smell of fuel inside the cabin, also around the car, no visible leaks (i checked thoroughly) no leaks.
Also the car jerked and the engine struggled, temperatures remained normal condition, fluids are ok, regardless i had to floor the pedal to keep the car from stalling.
I also had to resort in shifting manually as the change in rpm's got the automatic shifting confused.
When i got home i opened the fuel cap and it basically flew out of my hands of the pressure, my gas tank was severely pressurized this is normal from going to 125m to 2.300m but not normal since the EVAP system is supposed to relief the pressure and reuse the gasses ?
Anyway next day i checked again for leaks, nothing, only i noticed a huge fuel increase the last half hour from the day before im guessing from flooring the pedal 80% of the time...
I warmed up the car and made a small trip, did not get chance to make a bigger trip but this is what my scanner picked up from the live data (Bluedriver)
Purge command is going to 100% and short trim is going as low as 19% (according my info it should be around +10 and -10) mine is mostly going negative all the time.
This morning i delivered the car to my Mazda dealer for diagnostics, but to my surprise nobody knows what an EVAP system is, they had no scanner available and 3 dudes at the dealership where talking about changing my catalyst converter and their scanner uses Microsoft Word and they only have 2 licenses and currently they are with another dealership.
I even presented them with my findings and scanner data but i felt i was talking to a baby...
I was thinking i have a flooded charcoal canister, then again i did not monitor much of other data because of lack of time only because of the actual symptoms presented i monitored these sensors.
