Yes, you will get erratic idle, 2 of your cylinders are working property.
A simple test to check your injector, take the wire harness off the injector, put a ohm meter leads on each connector(2) in the injector. It should be within 3 to 6 ohm range, if not the injector is no good buy a new one. I used to rebuild them but the price is alot cheaper now not worth the trouble for a new one 35 to 55 dallors money well spent. If it shows good make sure the injector is geting power to the connector by using volt meter, ground your IGN COIL, turn engine over and see if pwr is geeting to it.
Once you resolve this problem and your engine is still running erratic then Yes, Check you IAC.

#4 of 11 '04 JGC 4.0 V6 Check Engine Light/Cylinder & Injector Trouble
Sep 19, 2008 (10:35 pm)
After a few days of hard rain my check engine light came on and will stay on at times and then start flashing and go back to a steady on. I got it scanned and it read a problem with the #4 cylinder and injector. I had the injector replaced and everything was fine for 3-4 days and the light went back on. Now more codes are coming up including the #4 injector which is brand new. Idling, reverse, and driving has lots of vibration and it's sluggish to accelerate. When I try putting the pedal to the floor to speed up the vehicle won't get any giddy up and just "coughs". I even tried using fuel injector cleaner. Is this a possible computer problem where it has possible gone on the fritz from too much rain water? Any help or insight would be appreciated before I take it to the dealer. Thanks.
