HELP!!! Having a high idle issue and can’t seem to fix. Codes are P0507 and P0123. Issue started about a week after replacing vacuum line and about a day after replacing the rack and pinion. I’ve cleaned the throttle body, changed IAC, changed the TPS, changed PCV valve. But I do notice when I take the Hose off of pcv valve and plugging the hose with my thumb the high idle goes back to normal. As soon as take my thumb off the high idle comes back. I have read somewhere online that someone has replaced a power steering pressure switch and it solved their issue. I can’t seem to find a power steering pressure switch on my system.
