06 Solstice - weird hesitation / bogging under heavy throttle

처리 내용

Solved! Having cleaned the MAF, checked the O2 sensors, hunted all over for a vacuum leak (here's a hint - don't spray carb cleaner near a disconnected vacuum hose that's actually carrying positive pressure. Your eyes will not thank you), etc., I finally pulled the NEW cam actuators back out, and saw this: On the left is the new Dorman exhaust cam actuator solenoid. The disconnected peace is a screen that's SUPPOSED to be attached to the solenoid. When I pulled the solenoid out of the head, that piece stayed in the head. Fortunately, I still had the old ones, so I put the old exhaust actuator back in. The car no longer sounds like it is going to explode and hasn't left me stranded. Also, my temps are down by about 10 degrees Fahrenheit. Unfortunately, the low-RPM / WOT hesitation problem I had before is back, but I expected that. Since this was acting like a vacuum leak, my theory is this: the ECU was trying to adjust timing on both intake and exhaust, but wasn't really able to do so f
