my buddy has an 01 and we pulled the intake off at the turbo. it was filled with oil from his cheap filter. could the intercooler be cloged from it to? also his his pickup has a lope to it sometimes. could it be electronics, injectors, fuel pump? anybody else ever have this happen?

 

how much oil? pull of intake sensors and clean em. I can't see the IC getting clogged unless there was a ISHT ton
