So after i installed headers/downpipes/exhaust on my 370z everything was fine for around 2 weeks... i then saw the CEL come on and about 3 days later went away... it did this a few times for next month then was off for a while... however last week it came on and stayed on and i checked the code and this was what i got
U0164 Generic DTC: Lost Communication With HVAC Control Module
and my AC also does not seem to work so my question to you is will nissan void this since i did header work and what not?
very nervous to take this in
