gas in oil

[sleepygene62]

been having problem with 95 5.2, due to poor idle i pulled the intake off to check belly gasket, was ok, took pan off to replace gasket and clean inside of intake and noticed two runners in the back were washed super clean by raw gas and belly pan right below that runner was also clean by raw fuel and lots of it, the rest of the runners and inside of the intake is filthy, i cant belive two injectors are stuck side by side, pcm bad? what else could cause this? should of tried a noid light before i ripped it apart, i havent seen an injector stick open like that, let alone two side by side, all 8 check out with ohms test, glad i pulled the intake anyway, found the fuel problem but whats causing it? pcm? help!
