The search for pulsars in a sample of pulsar candidates found based on a multi-year survey conducted with low (six channels; sampling 0.1s) time-frequency resolution on declinations -9° < δ < +42° was carried out with the Large Phased Array of the Lebedev Physical Institute (LPA LPI). LPA is a transit telescope operating at 111 MHz with a bandwidth of 2.5 MHz. Search, analysis and evidence of pulsar detection were carried out using a visualization programme of summed up power spectra obtained from the survey data with high (32 channels; sampling 12.5 ms) time-frequency resolution. 11 new pulsars with periods P₀ = 0.41-3.75 s and dispersion measure DM = 15-154 pc cm^–3 have been discovered. In total, in the survey with a low-time-frequency resolution for the period 2016-2021 in a blind search 203 pulsars were found, among them 42 new and 161 known pulsars. It is shown that in the search on the data with high-time-frequency resolution accumulated over a time interval of seven years, pulsars with a flux density of 0.1-0.2 mJy at the frequency of 111 MHz can be detected. When searching for pulsars with regular (periodic) emission at declinations +21° < δ < +42^o, all pulsars located outside the galactic plane having P₀ ≥ 0.5 s, DM ≤ 100 pc cm^–3, and the flux density S ≥ 0.5 mJy can be detected.
