Hows your hp feel. I had the same issue with my 04 rubi, bad mpg and low hp. Took it to the dealer and they found that the fuel pump wasn't providing the proper fuel pressure. It was only getting like 30 psi and needed around 50. They replaced the pump under warranty and man what a difference. I am now getting around 15 on the freeway and 13 in the city with 32" tires an automatic with 40,000 miles and a roof rack. The Roof rack really killed the gas mileage. I used to get around 18 on the highway.


This doesnt make sense to me, maybe its because its 1 AM and I have been up since 6 AM and I should be in bed, but if a vehicle was making less power it should be using less fuel, and then getting better mileage. I could see how a lower pressure pump could adversely affect power, but its just not making sense how that would also adversely affect fuel mileage. I'll have to think about this for a bit.
