Are you talking about the fuel injector resistor pack?

I changed my whole setup: piping, turbos, injectors, cams & cam gears, shortblock and intercooler and it seemed to fix the problem. I think it's most likely related to some sort of airflow turbulence issue that occurred with my old setup.

well thats one way to take care of it lol...its good to see you didnt give up on the car, i can imagine after so much time being down it would have been very tempting.

im hoping i have an intake leak, so im trying to trace that down

Not a Intake leak ! I gave up and took the car off the road today because I could not Dela with bad hesitations and misfires when i was crusing from 2200 to 2800 rpms

AEM EMS V2 and i have tried everything else

Damn that sucks man. I stripped some threads out in my lower plenum, prolly from taking the intake on and off so much changing plugs and gaskets, so mine has been down for like a month. I hope to get the plenum in this week and decided to go ahead and do the egr delete. I hope to be able to do more troubleshooting soon.
