Hello,
The engine on my 1999 Windstar 3.8L has been idling very roughly, sputtering and dying on cold starts; after it is warm it runs fine. It set off the check engine light, I stopped by autozone and they ran the codes and said it needed a camshaft position sensor replaced. Does that sound correct to any of you? Where is the camshaft position sensor? Can I replace it myself? It has 115,000 miles on it and hasn't had the plugs changed in it as far as I know, could that make it idle rough and then set off the sensor? Thanks for any suggestions!
