I need your expert help in fixing the problem i am having with my 2001 sunfire (2.4 L).

my car was working fine until recently when i noticed it idling high at 2000 rpm when started. after about 30-45 seconds, it drops to about 1200 rpm.

i have had the following changes done
MAP SENSOR
MAS SENSOR
and one other sensor that resides in the same vininity (forgive me , i am not a technical person).

what's my next step? any help will be greatly appreciated.

Hello ! well, you are doing it the right way.. probably the thread its "stuck" it is turning or not? try using a brake cleaner ( to dissolve the gum... ) do not use oil and do it wit care to prevent damage to the seal... Here the instructions: When installing new brake pads, caliper piston must be properly retracted. Using Piston Remover rotate piston clockwise until piston is fully seated. Ensure one slot in piston face is positioned so it will engage nib on brake pad. Install brake pads, anti-rattle springs and brake caliper. Ensure brake pads are properly positioned. Clean retaining bolt threads and apply one drop of Threadlock and Sealer. To complete installation, reverse removal procedure. Bleed brakes. here the view of your brakes (courtesy of Mitchel 1 )
