I bought this car couple of months ago with 113000 miles. I have already replaced
(OEM) SP, Cords, Rotors, Dist Caps, Air Filter, fuel filter, PCV, two front O2 sensors, timing belt, water pump and serpentine belt. Just replaced all 4 tires with Michelen and also had 4 wheel alignment. Recently had Fuel injection service. After having all the above, I still get 20 MPG on HWY and 17-18 in city. Also car rides OK on smooth road but on slight bumpy road, it really reacts. There are no noises coming out. I checked the struts at the shop and they are OK. Needs advise and suggestion on both issues.
