A note about the O2 Sensor extensions from eBay. Don't go by the color wire they used. They are a "pass-thru" extensions, and they work. But when connecting fuel wires, you'll want to see
what color wire on the extension is in spot 1 of the .connectors. In my case, Pin1 on the eBay connectors was
yellow, not red. I had assumed it was color coded and soldered the fuel wire connector to the red wires. This caused a no-start condition and a Check Engine Light. I'm not sure if other colored wires might be used for Pin 1 (spot 1 on the
aftermarket connector), but best to double check before tapping or soldering the fuel wire in.
In terms of the
spark plug removal - it was a lot easier than expected. The passenger side is definitely the harder side, but a 1/4 inch ratchet with 3 or 4 inch extension and U-joint made short work of it. The smaller diameter extension makes it easier to get to those coil hold-down bolts. And doing the job on the passenger side it's easier to remove the front and rear coils first. That gives plenty of room to work with middle cylinder (which is right under the intake manifold.)
Lastly, the JB4 bluetooth kit: I found that the bluetooth antenna needed to be pointed toward the driver for me to get it to work. (Point the end without the wires toward the driver.) I used some velcro on the JB4 box and the bluetooth dongle that seemed to work fine.
