One of the steps on my checklist of things to do when preparing to drop the cardle is to "Disconnect all vacuum lines that are not engine related". I disconnected the two that run along the rear of the engine compartment (go to the fuel cannister I think??). My question is what other vacuum lines do I need to disconnect, and where are they?

Thanks!

There's one from the EGR solenoid on the water pump side of the motor that goes to the firewall, and then to the air cleaner. Disconnect it at the solenoid.

Also, obviously, the big throttle body one

Other then that, I think that's it. Do a search for Vacuum lines; there's a good diagram floating around here somewhere.

Good luck, it's a fun job

the brake vacuum booster line, pointing towards the firewall about where the #4 spark plug is.
