Last weekend was busy. On Saturday I changed my alternator out (it burned up and I drove 40 miles on a draining battery). On Sunday golf ball size hail tried to destroy my car (it now has a few dozen decent sized dents in it), I changed my air filter, cleaned my snow screen, and cleaned my MAF sensor.
So all last week I have been enjoying a massively more responsive little diesel car. I mean, it is so surprising how much more power and zip it has. I'm talking literal surprise when I take off. Wheels spin. I get pushed into the seat. My eyebrows raise and I smile.
I used the CRC Mass Airflow Sensor spray cleaner. There was so much oil and junk on the sensor and in the housing. I sprayed and sprayed, and black kept coming out. I did that until clear came out, then let it dry before reinstalling it.
However, my fuel economy dropped a few. My fuel economy hasn't been great for a long while now, and I am trying to figure that out. I was hoping that it was the MAF, since it was so dirty. But I just filled up this evening and my MPG calculated out to 35. I usually get a pretty consistent 38.
So I figure there's two reasons. First is my foot became heavy because of the MOAR POWER factor. It's just so damn fun now. Second is that the computer didn't compensate (properly) for the newly clean MAF.
Is the second option actually an option? Wouldn't it automatically run better if the MAF was filthy and became clean?
