numerous cylinder misfires
hey so i have a cylinder misfire and it varies which ones they are. i can feel it on the highway it will be like a jerk or stumble. i can clear the codes and it the check engine will come on and it will be different cylinders maybe one the same. i also had fault code p0340. so i have changed the plugs, wires, cap, rotor and camshaft sensor. p0340 went away (camshaft sensor code) but still have misfires. anyone have any idea what this may be? oh i also have a small exhaust leak where my header meets the y pipe flange. would this have anything to do with it?

Check your fuel pressure.
Maybe try some fuel injector cleaner. (seafoam?)
There is a TSB (technical service bulletin) on plug wire routing, but, as you have replaced the stock wires, I am not sure if that would even apply.......
Throttle body spacer is a waste of money our the dodge trucks. Does nothing.
If you put it back to the stock tune, does it still do it?
