Cleaned all connections, dried them up, replaced spark plugs, checked for any loose connection, intercooler, vacuum lines. After replacing spark plugs i'we noticed idle is much better. BUT BUT BUT it still same freaking problem, turbo will spool a bit and than cuts off then will spool and cuts off. Feels like you driving the car and someone pulls you from the back. Also there is still noise present (sounds like piston slap) but it will be present, than will go away, then when i rev the car to 2-3 K it will come back.
.... I'm pissed, spend 4 hours trying to track down what's going on, but still no luck.
I wish i knew someone in Rockies area or Denver who can help me out, i mean not for free, but i can pay not much too.
