Just purchased this car recently, has about 170,000 miles on it, no problems other than the security light coming on and not starting for a short period of time, that is resolved. Now it will not climb hills, goes about 25 mph tops over any incline of any size, doesn't stall, you turn it off and it starts back up without any problems, around town and on the freeway it runs great, again as long as you are not climbing, even coming up onto the freeway entrance it has a little hesitation, not sure what to check

Check the fuel filter, it could be as simple as a clogged filter. Check the air filter too while you're at it.
Both of these have been replaced as well as a fuel pump, diagnosed by low fuel pressure, wasn't the problem, neither was the fuel filter, plugs, wires, etc. Any other ideas??
