Jeep Cherokee Grand Cherokee Trouble Codes
99 JGC w/ 4.7L
rc'd P0202 & P0207 codes having to due with fuel injectors! Does anyone know if this means the injector itself is clogged/bad or the control wiring?
Also, idle is very erratic, bouncing from 750 -1400 seems like a vacuum leak but can't find one ! could this be the AIS?
Any help is appreciated, thanks,
Mike

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.
Good Luck
