92 Z34 Codes 23 & 32 Simutaneously


Recommended Posts

I know what each code represents individually, but does anyone know what the 2 have in common and why they would both go off at the same time? Are both codes going off because the EGR is dirty/faulty, or are both going off because the IAT is faulty?

They are both probably dirty, and in due of a cleaning. Just pull it all apart, spray some carb or throttle body cleaner in there, and clean out the ports and what-not with pipe cleaners. Then re-assemble.
