Hi my name is tim, my girl friends car has has a high idle 1600 to 2000 rpm. She has paid a lot of money to have this fix before and nothing was fix. she had a new iac put in tune up ect. i tested all the vac lines and not leak and made sure they were connected right. i took off the egr and checked that it was good. i also checked the iac make sure it was good and it was moving. i put my scan tool in and check all the sensors and they looked fine. the only thing i can think is maybe the mass air flow sensor is bad or something with the pcm. if you have any ideas please let know. Thanks
