Misfire sss

[Tr^t0r]

ok, so ill start from the beginning, so i bought my 2000 eddie bauer about 1 1/2 years ago. its run great i had to swap out the air suspension awhile back, but about 2-3 months ago it began misfiring in cylinder 2 and 3. after replacing all the spark plugs and the coil packs for 2 and 3. the problem is still present, and now cylinder 1 is also misfiring................ i do have a coolant leak from just above what i believe is cylinder 1... so if anyone has any thoughts of why this would be.. or if anyone has the CORRECT cylinder numbering that would be awesome!

Cylinder numbers are as follows from front of engine passenger side also called Bank #1, 1-2-3-4

Front of engine drivers side also called Bank #2, 5-6-7-8

Sounds like you have either a. leaking intake manifold gaskets or b. bad head gasket, but my thoughts lean towards A. Any other codes come up?

if there is coolant leaking about the passenger side plugs, the coolant can get inside the coil bofot and flood the spark plug hole so the electricity arcs to the block instead of the plug. Fix the coolant leak and recheck all your plugs and you should be good to go. The wiring harness could also be corroded so look at that as well.
