Hello, so here is what happened. I NEVER press on the Gas on my cars. Never the type to go fast. I had just bought this Benz 3 weeks ago and today i sped up for the first time just to get in front of a car and my Check engine light turns on! So i opened the hood and i smelled, like burnt. Maybe oil or gas? The engine was HOT. I had only ran it about 15 miles. I took it to Autozone to get a Diagnostics and 1 troubleshoot code popped up! I got Code P0170! Anyone know what it could be? Maybe a dirty air filter? Or a dirty MAF? This car is covered by the dealership if anything goes wrong, so i can't replace or fix it my self or else the Contract would void. But i also don't want to send it in for a simple fix when all it needed was a cleaning. Is there any way i can take off the check engine light to see if it'll come back on? Or what should i do? The car turns on and runs fine! Maybe a LITTLE hesitant on accelerating? I wouldn't know! I just bought the car! THANKS FOR THE HELP
