I have developed an increasingly rough idle and a SES light. Took it to PepBoys and they diagnosed a misfire #6 coil pack. I just purchased an ignition coil, specifying #6. My question is are all 6 coils the same? It looks like the rear 3 should be different but I haven't started yet, the coil I have the connecter points to the side, I think the ones in the rear should point straight up. I appreciate the help!

The front and the rears in the 3.0L are different, rears longer only I believe but plug in from the side, 3.5L are all the same.

 

They gave me a front one. I took it back and got a rear. I've got the battery unpugged now to reset the code. Thanks!
