Stalling at idle,1993 E150EXETG Evinrude.

[sterreo]

Motor starts fine and runs on cold idle until it warms up, then it runs rough and stalls. Sounds like it has a miss in the engine when excellarating, the coils check out ok, would a faulty powerpack cause an issue like this. Also does this engine lean out at at idle in neutral(run on three cylinders)and which three shut down? Thanks

No...
If it has the black manifold gasket they will get hard and can cause a airleak, they where updated to the red or tan gaskets. Pull the plugs and start with compression test first,inspect the plugs for steam cleaning as these blocks do leak,make sure it has Champion QL78YC plugs. Report your results...
