Walker scanned my ecu, and it said i had sparratic detonation, misfiring in all four cylinders, running too lean, and also a possible boost leak. It also had a code for my diverter valve, and im suspecting that is the culprit. When i took apart the DV i found a O-ring that was busted, and im thinking its causing a leak in boost pressure. having a leak in boost pressure can cause all of those symptoms, anyone else have any idea?

It also seems to be running in soft limp mode

change out that o ring and you should be good. i ve had the same kind of problems. just i was running way to rich. but you could of fouled out your plugs also.

Well after what walker mentioned to me about the coil packs and the mass recall, im starting to wonder if it wasnt done. Im going to call gossett and check my service records to see if it was ever performed, then if it wasnt, chance is its the coils causing everything. The DV didnt help the problem, however the boost was kick ass.
