Rough Idle??
It's quite possibly your O2 sensors. If you kept all four, then you probably have your rear's hooked up backwards. The drivers side sensor should be plugged into the wiring coming from the passenger side and vice versa.
If you left your rear sensors out, did you move the original rear sensors to the front positions? These ones are hooked up drivers side to drivers side, with the provided harness.
The other thing to check is that you have you cats installed properly (if you ran cats). The 'slit' in the pipe should be facing the front of the car.
If none of that stuff, go back and triple check everything that you removed during the installation.
To pull your codes, check out post #28 of this thread

Here's a direct link from the Tech Tips section on reading codes.

Thanks for the advice I will get back under the car and recheck the connection on the sensors and make sure that I did not cross them up when I hooked them up to the sensors.Yes it also is idling rough.Though it was a plug wire off,but they are ok. Thanks again for the help.
