Automatic or manual transmission? Possibly the speed sensor is intermittently faulty?Record of when/mileage the valves were last adjusted? Record of timing belt replacement? You might want to do a power balance test + compression test.
As Mikey stated not much acceleration from 1 to 2k rpms. These 1.7L engnes are pretty ball-less when it comes to torque.
