p0172 system too rich 2009 c300
So I recently bought my 2009 Mercedes Benz c300 4Matic, and around 2 weeks ago the check engine light came on. The cars been driving smooth and nothing felt off, but I checked it just in case. It gave me the code p0172 and I got it checked by a shop and they said it was nothing and deleted the code.
After around 5 days the check engine light came back on with the same code. I cleaned the MAF and the intake part underneath with some cleaning sprays designed for the job. And now I have more codes corresponding to the original p0172.
Any suggestions??? The cars been driving well no problems, although I do think the gas is getting used up quicker.
Thank you!!!
