NASA's Kepler mission has identified 1235 transiting planet candidates. The method of transit timing variations (TTVs) has already confirmed seven planets in two planetary systems. We perform a transit timing analysis of the Kepler planet candidates. We find that at least  11% of planet candidates currently suitable for TTV analysis show evidence suggestive of TTVs, representing at least  65 TTV candidates. In all cases, the time span of observations must increase for TTVs to provide strong constraints on planet masses and/or orbits, as expected based on N-body integrations of multiple transiting planet candidate systems (assuming circular and coplanar orbits). Description: In this paper, we analyze putative transit timing variations (TTs) by Kepler planet candidates that show at least three transits in Q0-2. Kepler began collecting engineering data ("quarter" 0, Q0) for stars brighter than Kepler magnitude (K_p_) 13.6 on 2009 May 2, and science data for over 150000 stars on 2009 May 13. The first "quarter" (Q1) of Kepler data extends through 2009 June 15 and the second quarter (Q2) runs from 2009 June 20 to September 16. On 2011 February 1, the Kepler team released light curves during Q0, Q1, and Q2 for all planet search targets via the Multi-Mission Archive at the Space Telescope Science Institute (MAST; http://archive.stsci.edu/kepler/). The Kepler team has performed an initial transiting planet search to identify Kepler Objects of Interests (KOIs) that show transit-like events during Q0-2 (Borucki et al. 2011, Cat. J/ApJ/736/19).
