Okay, this one needs some more details
What did you do about the oxygen sensor
have you checked for stored error codes by shorting the aldl diagnostic terminal on the aldl plug (under the ashtray) witht he engine off and the ignition in the on position???
Furhter things to check when a crossfire runs bad:
general tuneup, air filter, fuel filter, plugs, wires, cap, rotor, module
Then there's the possibility of a vac leak, especially around the intake lid gasket or the throttle body base gaskets, also check the different vac hoses for leaks, easiest by just pulling them one at a time and plugging the port on the tb. sometimes people forget to hook up the thermac vac hose after removing and reinstalling the air filter base.
Also check the TPS for proper setting and check the coolant temp sensor in the front of the manifold, if you have the old type with the mushroom style connector replace it with the later weaterpack style as a safeguard even if the old sensor and connector are still good, these are known to be vulnerable to moisture and give bad readings
