2003 And 2004 Spark Plug Change Tips

You have a few different options. If you have small hands and good tools you can get to #2 without removing anything. Otherwise you will have to remove either the cowl or the upper intake manifold for access.

You might consider replacing all the spark plugs if it's time. You don't want a #3 misfire code in a few months because that plug finally wore out too.

Remember to only use Autolite or Motorcraft double platinum plugs. They must be double platinum.

Also make sure you inspect the plug wire and boot when you get it off for signs of tracking.

As far as tools to change the plug(s): 3/8" drive ratchet, assorted extensions, possibly a universal joint and a 5/8" spark plug socket. You can buy all this for cheap at Harbor Freight Tools. Probably in a spark plug kit or set. A packet of anti-seize for the plug threads and a packet of dielectric grease for inside the wire boots. A feeler gauge too. Start (thread) new plug(s) by hand or with a piece of vacuum or fuel hose to avoid cross-threading.

Thanks everyone for your advice. I changed the spark plug # 2. But, the shake was still there and the CEL was on. Then, I replaced the remaining spark plugs, detached the negative battery terminal and reattached it after a couple of minutes. This time, the CEL was gone and I do not feel any shake. So I guess that problem is solved. I did this yesterday morning.

I took out the car yesterday night and I felt that the first start took a bit longer time than usual. Is this normal and will it go away? What else could be done at this stage?

Well, how cold was it this morning, and did you change the wires?

I changed plugs and it got rid of my hard start issue, but I still need to change wires.

It wasn't cold in the morning. I did not change the plug wires. Will look at this over the next few days and will see if I need to change the plug wires. Thanks for the help.

Plug wires make a big difference if yours are original!! Also the coil issue can cause hard start without good strong starting voltage through the wires.
Save the other wires for a spare and get a $30-40 set that is premium quality. The boots are better and the wire is bigger. You can pay now or tow later ?
