You may have a fuel related issue that causing random misfires easy stuff first unplug your mass air flow sensor start car up with it unplugged see if your problem goes away.
If your RPMs will not exceed 1500 ..you might have a clogged cat ..can you monitor the downstream O2 sensor? ..or ..evap purge valve might be stuck closed ..easy to check both of those ..anyway ..my $0.02 ..good luck
