Question about 2004 Mitsubishi Endeavor
While changing the spark plugs lost a nut in the engine compartment could not retrieve with a magnet, is it safe to drive?

I would remove the intake plenum again and check with a flashight and a telescopic magnet in each of the intake runners. You should be able to see the valve stem down the intake runner. It may be necessary to remove the lower intake manifold to remove loose bolt.

The front three should be easy enough. They are right in front of the intake plenum. (big black plastic looking thing on top of the engine. The back three are underneath the intake plenum. It seems like a lot to tackle but it is really not that bad.
As always, if you are not sure you have the skills to attempt this go to a qualified mechanic. I did mine in an afternoon.

THEIR ARE ABOUT 9 BOLT TO REMOVE THAT SUPPORT THE INTAKE. 2 ARE IN THE REAR IN THE CENTER OF THE SUPPORT BRACKET THE 5 THAT ANCHOR THE INTAKE ITSELF AND 2 UNDER THE INTAKE THROTTLE BODY. ( 12MM) 3 HOSES ON TOP OF THE INTAKE TO REMOVE AND 1 SENSOR TO UNPLUG OR UNBOLT (8MM)THE ONE ON TOP OF THE INTAKE (TOP LEFT REAR). THIS WILL GIVE YOU ACCESS TO THE REAR PLUGS.
REMOVE THE SENSORS BRACKET OR HOLDER ( ON THE LEFT JUST LIFT UP TO REMOVE) AND SWING THE INTAKE TO THE RIGHT. UNPLUG THE PLUG MODULE THEN UNBOLT THEM (10MM).

I dont have scematics avail for this vehicle. Here is some info though. There are three at the front top part of the engine. You will see three black ignition coils over plugs (COPs) with a grey electrical connector connected to it. Onece removed, Below these COPs are the sparkplugs. At the rear of the engine, there are another three COPs. (coils). But in order to get to them, you must remove the intake manifold. its the large black plastic pipes atop the center of the engine heading towards the rear of the engine. This entire unit needs to be removed. This job is about $450-$860 at the dealer or auto repair shops. It's not an easy task!! Hopefully this helps!!

In the V6 engine, you'll require you to take the intake off to get to the rear plugs but other than that it is pretty much the same.
