I have a 2005 dodge neon. It's reading these codes. P0304 misfire cylinder 4, p2097 post catalyst fuel trim system high limit and p0344 cam sensor condition. If any had these same problems please tell me what did you get fixed to solve the main problem .

 

Hey there, anytime a cam sensor code pops up it's time to replace it. Cheap fix too, just clean the cam sensor area of dirt and crud before you replace it so nothing get's in there on the new seal & sensor

 

Inspect the #4 plug for fouling/excessive gap/crack in the porcelain to start.
