Hello, I've searched the forums but can't find a solution, so am reaching out to you all.
I have a 2003 Altima, 3.5 with the P0507 code, high idle. I replaced the MAF, the throttle body with a new TB not a rebuilt, and also replaced the PCV valve.
I clear the code with my scanner, completed the Pedal, throttle position, and IAC relearn with success, it idles around 700-800 RPM...UNTIL I turn off the engine. Once restart, the idles back up to 1200-1300 RPM steady in Park.
Do it all over again, several times, idles good, codes cleared, turn off the car and BOOM, high idles back, and codes throws soon.
Please help, have you seen this before and what helps?
