you either have an injector starting to fail, or one of the under valve cover harnesses is starting to disconnect itself because the lock tab is getting weak from being heated up and cooled down.......it is tough to diag without a scan tool but you could pull both your valve covers and check the harneses.....if they push in more than an eigth of an inch....replace them........if its an injector....you will have to have it doing it to even start to diag it and even then its not easy without a scan tool.......Marc
