There is a vacuum leak under the hood. If it's a 6 cylinder, look on the drivers side for a vacuum line that runs vertical with a 90 degree angle fitting to the manifold. That one usually comes off. If it is a V8 look on the battery side for a broken or corroded vacuum line.

There were several driveability
improvements made and Chrysler issued a TSB to address the issues.
There is a software upgrade that will take care of the problem. So I
would let Chrysler check it for codes and perform the upgrade.
Good luck, and remember rated this help.

Computer hookup should be the same and physically it's the same engine. Only thing I can think of to check on is the engine mounts (not sure but there may have been a change there. Also, make sure you keep the same flywheel position in relation to the crankshaft and that both flywheels are identical in every way including tooth count.
