Sputtering under load~

[Skrilla]

I just bought a 95 Grand Cherokee 4.0 4x4 automatic and only under load it bucks and heitates around 1-3k rpm.In neutral it revs fine.The service engine light reads too.I checked for codes and nothing came up.Any help would be appreicated.Thanks

Possibly the Map Sensor, just a S.W.A.G though.
