1998 Plymouth Voyager map sensor

Ok I have a 98 Plymouth voyager with a 2.4 engine in it. It is not the orig engine I have had the computer scanned at auto zone because when I am driving the van it feels like there is no compression after it gets warm I can put the petal to the floor and it will not move it does rectify tsself after a few seconds but its a continuious thing. Also if it is sitting for a long period of time in idle it will stall out. They told me that it has to do with the map sensor now I am confused on where this thing is located to see if that fixes my problem I have been told that it is 4 different sensors on my van. I cannot afford to have a shop to do it so I am doing it myself can you help with some kind of diagram toshow me where this is located?
Do you
have the same problem?

MAP sensor I believe is either on the firewall or on back of intake manifold. Should be a rectangular box. I had an intermittent problem with engine cutting out or not responding to throttle, especially in hot weather, and my mechanic couldn't diagnose it (he started with the MAP sensor). I found the wires to the crankshaft position sensor were brittle and nearly broken. I replaced it, and now the van runs fine. Not sure about where the crank sensor is is on your engine. On the 3.3 liter it's near the transmission bell housing, best seen from underneath, looking forward from aft of the crossmember, on the driver's side.
Was this
