Do you think my variocam actuator is stuck? I replaced only the solenoid some months back before I took it to a "professional"

Possible. If you have the Durametric software, you can test activate the VarioCam units at idle and watch the change in the cam deviation values.

I have activated the cams using the durametric before. When I activate # 2 it drops a little in RPM and regains nothing big. When I activate # 1 it almost stalls out the car. big drop in rpms and regains then drops again. What does that indicate, that the cam is already advanced and when I actuate it, it advances it to a stalling point?

If it did advance even further, you should see it in the deviation values.

I've attempted to activate the cams while view the values and for whatever reason I am unable to do so. Any thoughts on why it would almost stall out the car?

Because something is wrong with the cam timing on the suspect bank. Either the timing is off, or for some reason the DME thinks it is, either is enough to cause problems...............

Thanks everyone on the forum, my boxster is back up an running.

It turned out to be the variocam actuator, which in itself was a royal pain in the a--. to replace.

The former owner had been inside the cam cover and had stripped out one of bolts attaching the exhaust camshaft, so I had to replace the actuator by only removing the intake camshaft. An 8 hour job turned into a 16 hour job. But at the end of the day the car is fixed and she purrs like a kitten.

THANKS EVERYONE!!!! :dance:
