I believe it has ( 2 ) because the ignition system is EDIS ( Electronic Distributorless Ignition System ) on the 2002 Mercury Mountaineer V8
A 2002 Mercury Mountaineer has the Electronic Distributorless Ignition System ( EDIS ) With the 4.0 L , V6 engine there is ( 1 ) coil pack With the 4.6 L , V8 engine there is ( 2 ) coil packs
According to the 2003 Mercury Mountaineer Owner Guide : Both the 4.0 liter V6 engine and the 4.6 liter V8 engine have the Electronic Distributorless Ignition System ( EDIS ) So , on the 4.0 liter V6 ( 1 coil pack with 6 towers ) and on the 4.6 liter V8 ( 2 coil packs with 4 towers on each )
A 2004 Mercury Mountaineer does not have the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils . It has the Electronic Distributorless Ignition System ( EDIS ) with ( 2 coil packs ) and ( 8 ) spark plug wires

Actually it doesn't have a distributor , it's EDIS ( Electronic Distributorless Ignition System ) and has ( 2 ) coil packs at the front of the engine that are controlled by the powertrain control module ( PCM )

Could be a leaking vacuum line or with the pcv valve. It is possible that the trannsmission clutch packs arent dissengaging properly causing it to stall. PCV valve is a likely culpret with idle and stalling issues. Start there first.
