Need assistance in passing smog c280 sport
Hello everyone! Hope you are all having a good week.
I have a 1999 c280 sport that Ive been having a hard time passing smog.
Currently there are no codes/no check engine, yet I am still seeing an 02 icon flashing along with a cat icon on the obd2 reader. The major codes prior were a p0100, po442, p0110 before I ran smog.
So far ive changed the Maf sensor, air filter, re fastened loose intake housing near filter. Changed brittle vacume lines, changed oil.
Recent smog I ran, the small leak code was present also high hydrocarbons came out on report.
What other suggestions would you guys recommend?
