So, Finally had time to address this 0175 issue: cleaned the MAF & throttle body & then broke the retaining ring on reassembly 🙄

got a new MB retaining ring & installed

cleared code

have now put on an additional 330 miles since then & have no codes & the car runs like new! I drive mostly highway speeds (80-90mph) but some around town stuff, too (45-60)
STRANGELY - the car has always run Perfectly! Has ALWAYS run like new! Never a performance issue, only the check engine light on & that code!! Weird!
Anyway, guess I’m gonna call this one done for now & will go back to just enjoying the rides!!
Just an Awesome car!
Thank You for the MAF & throttle body advice!!
