Good morning
This is a post to reassure all of you who are afraid to do a tune up on the North* engine. It is very easy! i did mine this weekend in 2 hours (95 STS 85k). I changed the plug, plug wire, fuel filter and air filter.
Just go slowly.
These are the step i followed to change the plugs and wire.
#1 remove the engine cover (open the hood first lol)
#2 remove the strut brace. This is easy and gives you a lot of place to work
#3 remove the coil pack. 2 bolts on the back and 2 bolts on the side (10mm). This will give you easy access to all four rear spark plugs
#4 remove plug wire and change the plug. Do the plug one at a time. You should not have any problem removing the plug in the back. Use a spark plug socket, the one with the rubber to hold the plug in place and a extension.
#5 change the wire one at a time making sure you put it back on the correct terminal. This is pretty foolproof. The number of the cylinder is labeled on the block and the terminal is labeled on the coilpack AND in some case it is labeled on the wire as well.
#6 Put everyting back in place
For the fuel filter is is on the driver side of the car underneath the rear door.
#1 Remove the fuel pump fuse and run the car until it stalls. This will remove most of the pressure from the fuel line.
#2 Jack the car.
#3 Locate the fuel filter and remove it. I used a screwdriver to break the plastic thingy that hold it there but im pretty sure there is a better way to do it.
#4 Put the new filter in place using the new plastic retainer
#5 Dont forget to put the fuel pump fuse back!
145$ CAN for the wires
105$ CAN for the spark plugs
12$ CAN for a fuel filter
100$ CAN K&N 33-2086 this is a direct fit for the STS even tough it is not listed on K&N site.
The dealer wanted over 800$ to do all this!!! can you beleive it! I did all this in about 2 hours. Now the STS is even smoother at idle and scream at WOT.
Do you guys have any other suggestion for my tune up? I want to clean the injectors but i will probably go to the dealer for this since they have a pressurized washing system.
