Need the vacume line diagram not emmissions but vacuum lines

• First you want to open up the hood of your car
• Find the engine diagram sticker on the inside of the open hood and identify the mechanism that is labeled "EGR Solenoid" on the sticker.
• Find the "vacuum line" on the sticker diagram and identify its color. This is the line that runs from the EGR solenoid to the EGR valve.
• Locate the vacuum line inside the engine compartment of the vehicle toward the front of the driver's side. The vacuum line will be the same color on the vehicle as it is on the diagram.
• Follow the vacuum line from the front of the vehicle where it connects to the EGR solenoid through the conduit that carries it to the EGR valve at the rear of the engine compartment. The easiest way is to track the uniquely colored vacuum line along the path between its two connection points. The vacuum line connects to the EGR valve, which is the disk-shaped object located at the rear of the engine compartment
  on the driver's side.

9 times out of 10 your problem is going to to be with the MAF Sensor. You changed it, was the old one bad? If not try putting the old one back in. If you bought an aftermarket MAF and didn't replace with an OEM MAF, that could also be your problem. Recheck to make sure it's seated correctly, check the wire connection.
Unless the stickers have been removed, you should have a vacuum line diagram under your hood.
Here are what you should check from top to bottom.

• A clogged, stuck, or leaking fuel injector
• Faulty fuel regulator
• Dirty or faulty mass air flow sensor
• Faulty coolant temperature sensor
• Faulty thermostat
• ECM needs reprogramming
• Dirty or faulty oxygen sensor
• Vacuum leak
• Fuel delivery problem
• Incorrect fuel pressure

More often than not, vacuum line diagrams are located on stickers either under the hood or on the front cross member of the vehicle. If not, go to your local parts store and look up the diagram in a Chiltons Repair Manual. Some parts stores will even print the information you need

Hope this helps.

In north america it is under the hood on federal
emissions label

We do not have thses diagrams. There is a sticker under the hood that has the routing diagrams.

Have you looked around the engine compartment? Many vehicles have a sticker with the vacuum diagram on it somewhere there (usually on top of the radiator mounting frame, but sometimes on a fender well).

IF this is a case that the IWEs will not disengage, it could be the IWE solenoid or the vacuum lines to the IWEs. Could also be a problem with the vent lines from the IWE ( the other vacuum line that runs up into the engine compartment, and just hangs there ).

This is the block diagram of the vacuum lines for the IWE ( not actual routing ). You can use a vacuum pump / gauge to see if the lines will hold vacuum. Don't be surprised if the vacuum lines test OK, there is a TSB on the IWE solenoid where it could ingest water, and allow water in the lines, which will not keep the IWE gears disengaged.

Use a industrial vacume tester, check each port coming off of the manifold, run your lines.

there maybe a sticker in the engine compartment that shows the vacume line routing or you can go to a dealer and they can print one for you.
