I had found my problem as well
It was bad engine ground

So my mpgs are going down hill for some reason. Just replaced my alternator an ever since then I im losing about 100 miles a tank or more. the car smells of fuel pretty bad and theres quite a bit of smoke that comes out when I give it some gas.
My mechanic said possibly maf or ecu. And I doubt its the piping again because the power is still there. So any help thanks guys
