    Help! I have an 04 wrangler. 4.0 automatic. Was running fine until a sudden loss of power (engine light did come on). Replaced fuel pump with no results. Put diagnostic on and it threw codes for injection coils. Replaced coils and jeep started right up. Idles great - however as soon as you start to drive engine light comes and drastic loss of power. Was told to change 02 sensors, did that with no results. Any ideas/advice is greatly appreciated!

    Thanks

    Today it's P0352 - Ignition Coil 2 Circuit. Yesterday it showed P032,P0353,P0351 so I replaced the Ignition coils A,B,C (it's one part).
