1999 Mercedes Benz SLK230 4 cyl Two Wheel Drive Automatic 129 miles
I got a question for my 1999 mercedes slk 230 4cyl
the engine light is on and cannot pass the inspection and emission, I changed the catalyc converter, mass air sensor, air filter, reset the code when off, pass most of the emission but I still need to drive a bit more to completed the emission now suddenly the engine light is back on what should I do? Should I just reset the light? What is going on with my car?
