I just purchased the vehicle and noticed the idla air bypass would make a weird suction noise when first accelerating only time . in combination, as i accelerate i get a hesitation from time to time... When i come to a stop it "kicks down" twice and seems like its about to bogg out. Issue still has not been fix due to non funding for parts, as im a technician
