Can someone possibly tell me what's wrong with my 2010 v6 Ford escape. Once car is warmed up then it's shut off and restarted check engine light comes on and runs poor, rough idling and while driving it runs bad and shakes car. The codes that come up are p0301(cylinder 1 misfire) p0201(cylinder 1 injector open) p0443(evaporative emissions system purge control valve circuit). I already took out cylinder 1 injector tested for ohms was at 12, cleaned out injector appeared clogged at first.

 

Purge valves go bad alot, and if they stick open it can cause and vacuum leak and will lean out the cylinder. I would start by changing the valve or the they usually come from ford complete with canister and valve, maybe even with lines because they had so manyproblems. reset the codes and drive her she if that made a difference in the miss fire code as well.

 

I changed the purge valve, that took away the p0443 code, the other ones are still up and same symptoms.
