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.
