2003 Accord spark plug changing special tools? other parts besides plugs? Procedure? Common experianced problems?

There is a special tool, you can buy it from any parts store, about $5-$20 See picture of my favorite type below as there many designs.Lisle Spark Plug Wire Puller number 52990

Has it had a tune-up yet? (New spark plugs) If not, you're due. Also, have the shop test your coil packs - a very common problem with the Expeditions. I had my plugs replaced and No. 2 coil pack replaced recently for around $340. I'm a handyman, but would never attempt to change the plugs on mine myself - too much could go wrong- breaking a plug off, special tools, etc.
This should fix your problem.

you do need to remove the upper intake plenum to replace the rear plugs. haven't found a easy way or special tool for the job.

YOU NEED A LONG EXTENSION WITH SPARK SOCKET.YOU ALSO CAN BUY LONGER SPARK PLUG SOCKET AT ANY AUTO PARTS STORE OR SNAP ON HAS IT.

you have remove the accessories belt the plastic covers the spark plugs the valves cover the timing belt the pulleys then the pump.after that all back again retiming the engine etc etc........is very difficult procedure for a user.only an experianced person with special tools can do that.

No special tools, however the hard part will be getting the plug wires off without pulling the inner contact apart. Rotate the boots on the plugs before trying to remove the wires.

how to take spark plug wires off 2003 yukon xl

you will have to remove intake manifold to gain access to cyl 1 3 5. there are no special tools it can be done with hand tools. i would replace wires since you are there. intake gasket can be reused but if you wanna be safe or got high mileage replace

This requires a special plug boot removal tool so you don't ruin the plug wires, any auto parts store will have one, about $8

I am assuming you have the 3.0L Duratec engine. Although the job seems daunting, it's actually easy to remove the upper half of the intake manifold plenum. This took me about 40 minutes to remove the first time I did it, and leaves the rear three spark plugs wide open.

A good repair manual such as the Chilton's manual for the 1996-2005 Ford Taurus has the step-by-step. You should get a new set of intake plenum seals (from Ford or most auto parts stores, which may have to special order them) along with the spark plugs. The seals are a set oval rings made of silicone rubber. Yours may not need them but if you damage one getting the plenum off, or if they have shrunk with age, you'll be glad you got them. They're about $16 a set.
