DIY replace V6 ignition coil P0301
1. Remove the engine cover using a 3/16" allen hex wrench on the three (or less) nuts near the front. Now you can see Bank 1, cylinder 1 (pic)
2. Use some penetrating oil and unscrew the actuator and set it out of the way. Don't use a common phillips head screwdriver of you stand to strip the head. You need one with a short fat tip. (pic) To get some decent pressure on the two screws I used a 1/4" ratchet with a short extension. Don't let the screws drop into the engine bay.
3. Remove the insulated hose by pinching the wire clamps with your fingers. (pic), You may also unclip the wire than hangs in the way (tagged blue in pic)
4. Now you can get at the ignition coil. (pic) First, practice, by removing the coil from cylinder 2, one of the easy ones in the front (use a 10 mm wrench). If the bolt is stubborn slide the closed end of a 12mm wrench over the right side open end of the 10mm and that will give you some extra leverage for pushing. Then wriggle out the coil on cylinder 1.
5. (If you're not sure the problem is the coil you may be able to swap #1 with #2, hook everything back together and see if the trouble code switches to P0302. (Maybe you can, I'm not sure because I had disconnected my battery and the codes weren't coming up).
6. Install the new coil, a Denso 673-1301 ($70). Replace the bolt, the wiring harness, the insulated hose, the actuator, the hanging wire, the engine cover.
