I have an issue with my 2003 Mazda protege mazdaspeed where my car idles at around 1400 rpm but when I slightly press in clutch it goes back down to around 800 rpm which is I’m guessing normal. I have a code for apparently high rpm and a safety neutral switch but have already changed it out which I believe is the one on the transmission and when I plug it in my reverse lights stay activated not sure if these correlate. Thank you in advance for information on either of those problems
