After reading a lot of comments and posts ,I went to check some items on our vehicle.
We bought the 99' misty 2.5 l V6 used in 2001 and it has been to the dealer 3 times ..A/C and for CEL checks /diagnostic code reading .Not ever was the coil removed by me ,
I did a lot of general maintenance myself ,after reading posts I looked at the coil and found the braided ground wire just hanging there .. I bolted it back to the coil . Car appears to run smoother now ,thanks to all of you helping other owners pointing out many important details .
