I have lack of power and misfire when I first take off. It is worse when car has sat for awhile. It has a new fuel pump. I've also had the fuel pressure checked and an injector balance done and it all checked ok. No fuel pressure drop or restrictions. It has a new fuel filter and spark plugs. It seems to drive a little better after 5-10 minutes but still feels like it has poor power. When It's under a load I feel it act up the worse. It has history misfires on 1 4 and 6 cylinders. Can a bad cap and rotor cause this?
