Can an ecu lose its tune? I purchased my car 2 years ago and it had the air and egr programmed out of the ecu and the components removed. Lately my car has been throwing a p0404 and p0405 code which is a non functional egr system. Why would my car do this and is there any way short of tuning it again to get it back?
the tuner forgot to turn off all the codes. could be something else tho, cuz 2yrs thats a long time to not get codes and then all of a sudden get them
can't tell unless you look at the tune tho
