Question about Chevrolet Blazer
It was something that takes a lot of time and money to diagnose.Emissions requires the truck to have an EGR valve (exhaust gas recycle) and this deposits gunk (carbon residue) on your MAF (mass air flow sensor) If you catch it in time you can use a carbon cleaner from Autozone or checker Lightly on the MassAirFlow sensor. If not in time you may have to have either the MAF or EGR valve replaced and these are expensive. After a long period of time being undetected eventually the EGR valve will start smelling like sulfer, this means its to late to clean and save.
Thanks for contacting Fixya.
