you have GOT to be talking about the third generation 3.0 liter v6. You have to remove the intake manifold. If you don't know what that is, it's that silver multi tube thing that is right in front of you when u pop the hood. If you don't know what u are doing, don't even attempt it. It SUCKS. take it to a garage, it will cost around 50 bucks or so, but it is way worth it. It's actually going to be 400+ dollars to do the spark plugs and wires from what I have heard.
Every 30,000 miles except platinum plugs
You don't. The gap is not adjustable.
You can remove the spark plugs in your 2003 Mitsubishi Eclipse by turning the spark plugs to the left. You should use a 5/8 deep well socket. The spark plugs will come out.
2002 galant , can't find the spark plugs
I have 1994 Mitsubishi eclipse and have no spark i change cam and crank sensor but still no have spark can be icu
If you dont know how to replace spark plugs I recomend you go to someone that does and have him show you because you might do more bad then good trying to change them for the first time.
All depends on what kind of spark plugs you have. It could either be 30,000 miles or 150,000 miles.
The left side of the motor.
Once on 1-2 year on regular spark plugs. Once every there years on High end spark plugs.
