doubt its the o2 sensor. some more info would be useful in diagnosing the problem. before you starting experiencing the problem, have you recently done any work or install anything new? what are your mods? have you tested the iscv (since the car ran after you unplugged it)?

mods are eagle rods, je pistons,brian crower valve train intake/exhaust ported,780cc injectors, aero fuel pressure reg.,gt45r turbo, 4inch catback exhaust , tublar manifold with 50mm wastegate,custom made alumina hard pipes, vpc/safc, aem wideband, greddy profec b boost controller. car runs like has a boost leak, because on boost gauge is reading 10 when normally reads 20. Would the idle control val make the car run pig rich? i have no adjustment with my safc anymore, its like if you try to adjust the car will lope up and dwn.
