The only things thzt showed up on the engine scan were, Map sensor low voltage, both crank sensors, and low voltage at the cam sensor. I am thinking of putting a new MAP sensor in it. See post below about Fuel filter and Camsensor for more explanation of my problem. Thanks for any advice or suggestions.

Was a coil for me ! Same symtoms after wires/plugs change !!! Like a misfire. Mind 95's can't detect misfire and indicate by MIL light.
Check grounding of ICM and PCM.
In my case engine heating up lead to bad contact and coil burned, resulting in intermittend weak spark in cyl 2+5.
It all started in a very big rain, so i deducted it's electrical.
