Need to know the Locatons for Vaccum hoses I have

This is for a 3.1 liter engine.

Probably a Vaccum leak which Vaccum hoses need to be checked or Vaccum hoses needs to be reversed or it could be the position motion sensors.

The coil pack should should be the device you plug your spark plug wires into. if it is round, then it is a distributor not a coil pack, if it is square and looks like there are relays coming of it, it is a coil pack. to replace this, you simply mach the wires to the corresponding diodes on the new device, unscrew the old one and screw in the new one. plugging in any connecters you might have forgotten.

Sounds like either you have a vaccum leak or the idle air control valve is acting a fool. I'd start by looking for a vaccum leak. This is easy to do. Take a can of carburetor cleaner and spray it around all the vaccum lines, where they are connected to something and on the ends of every hose. If you spray one line and your idle speed increases for a moment, you've found the leak. just replace the hose. Shouldn't cost more than $3. That's where i'd start. Sounds like you have a minor vaccum leak.

possible vaccum leak, check all vaccum hoses for cuts aor being loose. You can take a can of starting fluid and start you car, let idle and spray around the hoses and the intake to find vaccum leaks.

check all vacuum switches for leaks

More them likely you have a vaccum leak, check vaccum line that gose into fire wall under hood make sure it has vaccum, if don't find vaccum hose and repair, if it does check vaccum hose under dash follow it make sure it's plug in, if it is could be a bad vaccum pull off or bend door or the selector switch. Good luck hope this was helpful.

Here is a list of some things that can cause it,
Emmissions system not functioning properly,
Faulty secondary ignition system
Fuel injection system in need of adjustment
Vaccum leak at fuel injectors, around intake manifold, or vaccum hoses
Clogged fuel filter
Weak fuel pump
To test for a vaccum leak, get a can of starting fluid, with the engine running, spray around the intake manifold, the vaccum hoses, connections and fittings, where ever you spray and the engine rev's up a little, you found a leak.

the vacuum modulator that the vacuum hose connectes to at the transmission has a ruptured rubber diaphram, replace the vacuum modulator and the vacuum hose.

You can generally find a vaccum leak by pressure testing the system. Most auto parts stores sell a vaccum tester relatively cheap. Or you can take it to a shop and they will pump your sytem full of a uv sensitive die and then use a black light to find the leak. If it says vaccum leak at engine on the vent solenoid then all you need is the schematic of your vaccum system to find the solenoid and you should find your leak theoretically.
