there are a few answers to the problem. First- the injectors are controlled by a computer. The computer needs a steady supply of electricity to fire the electronic injectors. If system voltage is occasionaly low (alternator, battery or wiring problems) the resultant dip in voltage may fail to trigger injector firing intermitantly. Second- If the car has been used to "jump-start" another car recently, it is possible that the ground circuit involved in computer operation may have been damaged. This might not show up as an error code at a shop but is still possible for them to diagnose. Third- injectors that may have been exposed to a voltage spike (or are simply getting old) could begin to occasionaly misfire. It's very hard to determine exactly which injector may be responsible and you could end up replacing them all. There are rebuilt injectors available on the market.
The other possibilities are ignition wiring problems, worn distributor shaft bushing, plug fouling due to either the wrong heat range or, oil fouling.
