Scratch noise/delay when gas pedal is pressed
I own a 2014 Mazda 2 sport manuel trans, 90,000 on the odometer. Recently noticed a slight scratching noise & slight delay from the engine when I press gas pedal in neutral for about 1 second before it actually starts revving. Also, I noticed its getting a little sluggish when accelerating not sure if the 2 are hand in hand issues. Never had a check engine light (knock on wood), no issues and general maintenance has been kept up, any information would help thanks!
