Hey i just picked up a 91 lx and there are two vacuum lines under the intake that are cut and plugged with bolts. Where do those vacuum lines go or should i even worry?

 

If you are looking at ur engine and they are on the left side I would imagine they are your heater tubes. Mine are routed to eachother with a u-tube and clamped down, I could be wrong....or it may be you ac lines also...Idk...anyone else have an idea?

 

the vacuum lines that connect under the upper intake on the back go to various things around the firewall. anything vital to keeping the car running is routed off the vacuum tree, hanging from the firewall a little to the right of the motor.
