check to see if all the plugs in engine bay are connected, check for vacuum leaks, like torn boots in the airways... check to see if the MAF is connected properly, if the oil dipstick is fully inserted, the oil cap is tight... check the airfilter, see if it is clogged up... next thing in order would be to see if the all spark plugs are firing and the coils are good... then, fuel rail, fuel pump, fuel filter...
with rough idle, you should see something on the INPA - is there anything?
