That sounds like a soleniod or more like a lazy soleniod since you said it works sometimes. I used to get that in my car and it would only happen in like 2nd gear. The soleniod gets lazy due to the heat and it sticks or something like that , Iam not sure.

You know, I am experiencing the exact same thing.

At first I diagnosed it as a ignition problem, so I replaced the leading coils (which weren't within spec anyway), ignition harness, sparkplugs, and spark plug wires.

Car runs a lot stronger, but the problem is still there. What Street King says about being a lazy solenoid is most likely right. And since it only affects the first turbo it could be any of, wastegate, precontrol, turbo control.

I'm even going as far as thinking of a bad actuator.

It happened to me and i switched around solenoids and fixed that problem and caused another
