Please help, code po 305 on my 2010 ram hemi.
150,000 km been to the dealership twice and can't afford them to keep getting this wrong.
They replaced ex manifold bolts( guess they needed to be fixed anyway)
Still no improvement, they replaced plugs still has not fixed issue.

My truck ran great up till 2 weeks ago,under heavier acceleration it starts to really crap out.
Anyone had any experience with this issue?

 

Code p0305 is a cylinder 5 misfire. Sounds like you are dealing with an incompetent dealer if they cannot properly diagnose.

Here is some info.
