[QUOTE="dpancer, post: 14635189, member: 143413"] Finally some good news. The problem was the bypass actuator. The fuel from the frps blow ate the diaphragm causing it to stay closed during idle. Obviously this also caused a vacuum leak. This caused more air to be pushed into the cylinders at idle than normal causing the fluctuating rpm. Pretty dumb of me not to check this first bit its not one of those things that comes to mind when you first hear a strange sound in your bay. By manually holding the actuator open and blocking the vacuum line the car sounded and idled properly. However, I'm still not sure the blower is suppuse to sound like that when the bypass valve is closed during idle. Can anyone with a ported eaton manually CLOSE their actuator and take a video of the sound for me??? All though it has always sounded like rotor or housing contact when I did this in the past, I have no idea if its normal or not. Perhaps a new blower is still in the cards. [/QUOTE]
