Engine Performance problem
2002 Hyundai Elantra 4 cyl Front Wheel Drive Manual 118000 miles

I am losing power when going up hills and when you first pull out. The rmp's are fine, it idles fine, but just looses power. I can have the pedal all the way to the floor and not pick up speed.

Take top timing cover off and check belt condition if you haven't already changed it. if that's not the issue check fuel pressure if fuel pressure is less than 49.8 psi you have a fuel issue. then change fuel filter if you haven't already then recheck fuel pressure. If that still doesn't fix it check for a fuel blockage and finally key in on the fuel pump. Next check for a clogged cat or resonator. hope this helps
