Hi,
I have been visiting your forum for awhile and learning many troubleshooting tips. I am currently doing an overhaul on the intake system to hopefully eliminate vacuum leak and rough idle concerns.

Should I remove the left and right wiring ducts as a whole unit? If so, I noticed one connector on the driver side in front of engine block is not connected to anything at this time and was wondering if it should be connected. Another connector on the passenger side goes in front of the engine block and seems to go under the engine. Any help with the wiring duct removal process would be greatly appreciated.

Thanks,
Ernie
