Thumbs down Uh-Oh.... Port actuator problem?

Some people may remember a post that I dropped on an actuator thread, last week.

(If not, don't worry, the question's the same)

Port actuator for rotor 1 (FRONT) is stuck OPEN; actuator for rotor 2 (REAR) is CLOSED; Non stock exhaust, no cat, useless air pump.

After I yanked the entire intake plenum off, I cleaned everything and reassemblied, fine. Started it up, and there was the usual smoke from various cleaners. One it started self-idling, I noticed that there was more brap-brap-brap than usual... Then, while it was idling, I reached in and popped open the rear actuator, and the idle somewhat evened out.

So.... This means that I'm running one open, and one closed actuator. Hm.

Is this a problem? Pros? Cons? Random, mind-numbing babble?

Hm... Just checked the vac. Teed a Boost Gauge off of the BCS, and it reads 18psi vac.

Hm, I say.

Hm, Indeed.
