I'm trying to locate the mass airflow sensor because I think this may be the cause of my rough running forester. But I've checked online and can't find a diagram of where it is on my car. I found a device that I thought was it on the throttle body area- when I pulled it, it looked like a metal mushroom and no sign of wires. It was dirty so I cleaned it, but I don't think it is the MAF. Maybe I don't even have one?
I dumped half a can of seafoam in the gas, and now I'm going to seafoam a vacuum line.
Thanks for any healp and/or diagrams.
