Installing it was a pain, the hoses were hard as hell to remove.

1. Change timing belt
2. Change plugs (use NGK Pt)
3. Change wires
4. Change other belts
Fuel filter is by the battery. Easy to do. Bought mine at Autozone (cheapest.)
Air filter should be replaced if you haven't in a year or are in areal dusty place.
Might want to consider replacing fluids in tranny, diff and brakes. Also have radiator fluid checked to see if it's still ok (Good mechanics have the instrument.)

Not sure if you want to spend that much cash but if you do they are well worth it. Made a huge difference for me. Gas mileage went up, better response from the motor...overall the engine just seems to run better.

My mom's truck was missing last time I visited around christmas time....her bf, who is a desiel mechanic didn't really think much of changing the wires, as they looked ok......however, after changing the wires.....Miss was gone.
The only word of caution I have for cleaning the butterfly plate is let the car sit for a little bit to get some of the cleaner to air out......before you start the car.

I greatly valve your opinion, you really helped me with the 95 legacy thermastat problem I had back in Dec, 2001. (See Archive)
Anyway,I will replace the wires as soon as I can get some. No one has them in stock, (maybe that's why they were not replaced while at the dealership??, who knows?), so I've ordered them from the local NAPA, who can get them end by Thursday. I figure at least I can find out if the wires are the problem, even if I am not using OEM wires.
Also, I've notice that the missing occurs only in the afternoon after the engine has been at runiing temp. for about 15 mins. I haven't notice the missing in the mornings.Could it be that the insulative layer on the wires has degraded and the missing only occurs after the wire reachs a certain temp? Just a theory.
I will the results of the new wires after I install them.

Let us know what you find out.

A review of what I have had done... A tank of gas with fuel injector cleaner added...
Tune-up at dealer.... plugs, air filter, fuel filter, air control valve, and fuel injection service. Included in tune-up was plug wire inspection and timing check. After driving home with the miss returning I call the dealer, they told the wires looked ok, but could be the problem.
Cleaned butterfly plate with carb. cleaner and as stated above replaced wires.
The miss occurs while crusing at road speed around 2200-3000 rpms. It is more noticable in the afternoon and during times when the outside temp is 65% F & above. NO change in gas consumption, it cranks and idles fine.
Any help or ideas are welcome!!!

Air Filter -- Puralator
Oil Filter -- Puralator
Oil Change -- Castrol GTX
Coolant toped off -- Phosphate free antifreeze and distilled water
Spark Plugs -- NGK standard
Plug Wires -- Love the Yakamha(sp?) wires but hear Magnacore are premo
Positive Crankcase Ventilation Valve (PCV)
Top off ATF fluid and Gear Oil
Top off tire pressure
Visual check on EVERYTHING -- clues you in on future repairs and maitanace
Thats my general 3,000 mile tune up.
Here's my higher milage tune up items.
All 3,000 mile tune up items
Thermostat -- Genuine Subaru Part
Fuel Filter -- Puralator
Accessory Belts -- Whatevers cheap
Change Differential Fluids (dont forget the rear for you lucky AWD peeps!)
Change ATF or Gear Oil for you lucky 5MT owners!
External Transmission Filter -- Puralator
Brake pads -- Had good luck with Raybestos
Brake Rotors if needed
And again the visual check on everything.

Sorry to hear it wasn't your wires.
When did the car start to do this miss?
I personally don't care to give as much trust in the dealer.....as some do. The only thing they have I don't......Select Monitor.....if I had one of those bad boys.....I'd be golden.

No 1. could be alleviated by removing excess carbon buildup
No. 2 would require teardown & [partial] rebuild.
If higher octane gas eliminates the misfire, then either of the above are possibilities.
