zetecvacuumtz6.jpg user_offline.gif If it's equipped with the 2.0L SPI engine (eighth digit of the VIN is 'P'), the most common place for a vacuum leak on these engines, is from the PCV hose that runs from the valve cover to the back of the throttle body. Where it usually rots through is the elbow at the back where it connects to the throttle body. Hope this helps. The only place i could find any views is here. vacuum hose diagram - Focus Fanatics

Is sluggish and has a hard time shifting


Major vacuum leak.
Check the vacuum diagram that is printed on a sticker under the hood.
Most importantly, check the big vacuum hose connected to the brake booster. Look for a disconnected hose and missing hose clamp.
There is also a vacuum modulator on the side of the transmission. the vacuum hose is disconencted or the diaphragm inside the modularoe is ruptured. ($20 AutoZone).

Vacuum pump diagram 2002 ram


It is very likely that the vacuum hoses are the problem. The only people that have a manual with the diagram you need is a dodge dealer, contact the service dept at your local dealer and they will probably photo copy you a diagram from the service manual.
