My 2005 Nissan Maxima does not acelerate like it used to when I step on the gas pedal.

Question

My 2005 Nissan Maxima does not have the poswer it used to when I try to punch it after 60 mph. It seem to be struggling to go past 60mph and could see the RPM stuck between 2 and 3. Service engine light came with codes p1800 and U100. Can some tell me how toresolve the issue without getting ripped off by the Dealer?
