"injection problem"

when starting the engine lights "injection problem" and "Check ESP", the car goes in spurts and jumping speed engine. Diagnostics produces an error "po 313 misfire detected with low fuel". tell me what the problem is and how to fix it, thank you!
 
error disappeared after I took off and put the same throttle and the same candles, trains a week, and again today there was the same problem, what should I do?
