2006 Taurus P0351 need help!

Changed out the coil today and erased the codes , and took it out for a test drive for about an hour. Everything is going fine so far... hoping for the best.

I hope it is fixed. Lately have seen more and more oe parts failing. Pretty sad. Sometimes it is a high current problem causing excessive heat to burn out components. Have to do current ramping with labscope. Let me know how you make out.

Drove the car back and forth to work today, ran very good. Typical erratic idle, but no misfire or check engine light. I think I got it! Thank you for your help autojoe!

Erratic idle? Thanks for getting back to us.
