I live in a 3rd world country and the mechanics are not very trustworthy. I've spent so much money already, more than my '95 model is worth. My biggest problem right now is that I am getting less than 15 MPG on average. The car has approximately 600 miles on a rebuilt engine, I had new oversized (.030) pistons and rings, gaskets, etc. The cylinders were honed and the fuel injectors cleaned. I am not running with a catalytic converter (bypassed). I am wondering if those two hoses in the picture need to be plugged into something important. Please help me, 15 MPG is totally ridiculous for a small car.
