My car started idling inconsistently between 500 and 800 rpms, going up and down. Sometimes stalling when in reverse or hard turns when parking. My friend says it could be the MAF sensor. Any opinions?

 

might be the throttle body, the dealership changed mine,, because while idleing sometime it would drop and come back up..

i have a video of that i will try to upload it

 

its 1.7mb don't know were to host it, my free website won't accpet movies and i can't attach it here i even compressed it to 350kb ,, send me a pm with your email and i will send it to u if u want it

okay found a way
i uploaded it the only way for the file to be accepted was to be renamed, u can rename it back to zip after u download it

using windows XP open go to Accessories > Command Prompt,, type
rename "drag file here using your mouse" idle.zip
click enter

extract the file

 

Have you recently disconnected the battery? Mine did something like that when I skipped the "learning" procedure after disconnecting battery and resetting computer. It went away after letting the car relearn the idle and fuel trims as instructed by the manual.
