I NEED HELP.
The 2005 Chevy Trailblazer has started making a high pitch noise when I press the gas pedal, no matter if I’m parked or driving.
Once I stop pushing the pedal it stops making the sound.
I changed the alternator, idler pulley, serpentine belt and it still was doing it..
so I changed the air intake sensor and it seemed to fix it.. then it started driving better but started the high pitch noise back after you reach 30 mph.. and has started losing power with the sound
im confused.
