Well I have a 2006 Caddilac CTS that has been rough on occasion. I plugged in my BAFX purchased Revain OBD diagnostic interface ($20) and said I had misfires on cylinders 2 and 5. I took the car to my buddy at the shop and he wanted $650! Crazy since it can be difficult right? Some good youtube videos on changing coil packs, I followed the one that takes the entire distributor off (wiper etc) was hesitant at first but it was actually a breeze. You will see other reviews of these coils on 4 cylinders and those reviews were good. Instead of replacing 2, I replaced all 6 for less than the cost of an OEM spool. I also replaced all 6 spark plugs when it was removed. The car drives perfectly. Got my approval.
