stalls,rough idle, spark plugs wet, engine light (multple cylinder misfire), idle speed variation.
Replaced air filter, pcv cleaned, plugs, wire boots,oxygen sensors (upstream-due to lean condition,low volts), & fuel filter

I had similar problems and had to replace the intake manifold gasket. The problems have stopped since. Hope this information helps.
