You cant set it manually, its electronically done by the computer so its always right. If you have a driveability problem suspect something else (fouled spark plugs, dirty injectors, clogged fuel filter, weak fuel pump, bad fuel pressure regulator, low compression, etc), but if you're certain its the timing then varify the crank and camshaft position sensors are both working correctly. Also check the timing chain, if its worn enough to jump time and your camshaft is improperly syncronized to the crankshaft it won't run well (if at all).
