Mirage sedan losing power
Hi guys.
Im new to this forum. I own a 2016 mirage sedan and noticed that my car is losing power. Everytime im in 2nd gear it doesnt reach the redline and stays at around 5k rpm and doesnt go any further. I do autocross and circuits as well so it is important for me to reach the full capacity of the car.
This is an on and off situation and ive been coming back and forth to my trusted mechanic but it seems they cannot pin point the main cause. If someone had experience the same thing please let me know.
As of the moment we have tried to replace the following to isolate the cause.
Sparkplugs
Gas tank was cleaned
Fuelpump motor was replaced
Fuel injectors cleaned
Throttle body cleaned
Clutch assembly replaced
The mods that i have are just headers and air intake.
