Made sure all the leads were in the proper place, and traced them all. Still ran shaky... even checked the coil pack wires to make sure I didn't loosen them or disconnect anything accidentally

Just to be on the safe side I am going to check plugs to make sure they are not too fouled.

 

Christ that was a tight fit, even with the coilpack out. I don't know how you guys did the job with it in place!

Arch: it's worth looking at the plugs when the engine is running after you're done checking everything. I had some misfire codes and saw the plug on cylinder 7 pulsating while running. Cinched it down and those went away. If it ran fine before odds are (if you're anything like me) you knocked something loose.

Here are the O2 sensors...fronts up top, rears down below. This look like a normal amount of residue/corrosion?

 

Keoni004 - Great job! Your old Oxygen sensors look a lot cleaner than my old ones! My rears were covered in wet oil when I pulled them, but the fronts were dry and very sooted/black.

 

Well, before I changed the plugs I checked the ECU and got p1316 as well as p0304 (cylinder four misfire).

Pulled the plugs and this is what I found

Passenger side plugs:



Drivers side plugs:



Replaced the previous plugs which were Standard NGK with the better NGK V-Power plugs.

I did ask specifically for the Bosch +4's or the tried and true Champions, but no one had stock available, or it would have taken two to three weeks

Rover runs smooth, just need to clear the CEL now

Thank you for all the help
