There is an injector driver, located above the intake manifold, towards front of engine, on driver side. Has an electrical plug on top. This may be intermittantly failing. It controls oil flow to your injectors. Very common part to go bad, and will also give symptoms you describe. It is a bit tricky to change, as it is 3 pieces. And in a bad place. Take your time, and dont get mad at it. Should take about 45min to an hr first time around.
