- With the engine running, turn the steering wheel hard right. This will be self-explanatory in the later steps. Turn engine off and allow to cool several hours.
- After positioning wires and hoses out of the way, get a 1¼ inch open end wrench. Slide under the vehicle at the rear of the left front tire that has been turned hard right. Locate the left side exhaust manifold, at the rear of the manifold you will see a 1¼ nut holding the EGR tube to the exhaust manifold. Using the wrench, remove this nut from the manifold completely. Now back to the top side of the engine, using a screw driver or other pry tool, get between the valve cover and the EGR tube and pry up gently (remembering the valve cover is plastic, don't pry too hard or valve cover damage will occur). I was able to use my hand to pull up on the tube enough to clear everything. I have read the removal of the EGR tube nut is not necessary, in my case it was. I couldn't get the no. 8 coil off the plug. With the EGR tube nut removed, and a little clearance by pulling up on the tube, the coil came right off. I am getting ahead of myself here.
- Using a 13mm socket, remove the two bolts that hold the coil cover in the middle of the valve cover. With this cover removed, the 4 coils are exposed. Note the wiring harness on the coils - the harness is shaped like the cover and must placed back in the proper place. Unplug the wires from the coils by pressing on the tab at wire end of the plug. Repeat this process for all 4 coils. Using various extensions and a swivel with a 5/8" spark plug socket remove the spark plugs. After installing all 4 new plugs and coils, pull the wires on each coil to be sure the wires are securely plugged on the coils. Now for the famous words "Reverse procedure". There are a couple of points of interest - On the EGR tube when re-installing the nut, I was able to hook a finger on the small hose tube (remember the hoses I disconnected on the EGR feedback sensor) and pull down while I started the nut. When installing the hoses on the EGR feedback sensor, notice on the sensor itself there is a large and small connector for the hoses - large hose goes on large connector, small hose goes on small connector.
- We are at the right side of the engine. Start by removing the battery. Remove the starter solenoid by removing two 8mm bolts that hold the solenoid to the firewall. It isn't necessary to remove any wires from the solenoid. Remove the wiring junction box under the solenoid by removing two 8mm bolts, unplug the single wire on top of the junction box and move the solenoid and junction box to the right fender as far as possible without stretching or pulling any wires. Remove the transmission dipstick.
- At this point, I read to drain the coolant and disconnect the upper radiator hose and remove the heater hoses. I didn't do this step, I found it was not needed in my case. Using the 13mm socket, remove the coil cover in the middle of the valve cover exposing the coils and the rest is like the left side. There is no EGR tube to contend with on the right side. I had more clearance on the right side than the left side. The right side cylinders are numbers 1 - 4, no. 1 at the front of engine and no. 4 at the rear.
I personally don't see how anyone could do this with the engine hot as you will get "up close and personal" with the motor before you complete this job.
