What can be the problem ?

Question

I'm getting codes p0305 and p0300 on my 03 dodge grand caravan. Its driving okay at times but when I start it, it now has a strong gas smell. Spark plugs and wires and coil pack are all new.

Answer 1

P0300 Random misfire

P0305 Misfire number 5 cylinder

When it start there is a strong gas smell, It is important to have the fuel injector check or the fuel leak resolved. A misfire condition strong with a gas smell that leak has to be found, it would also be a good start to check the fuel pressure regulator at its vacuum connection for leak into the intake manifold.
