It could be but usually you would get a check engine light for random multiple misfire, replace the fuel filter and then try it, if no improvement then do a good tune up, it is hard to diagnosis a poorly tuned engine. If that didn't help then you will have to have the system checked with a "live data" scanner so you can watch each sensor work and then replace the ones that are not up to specs.
