I just had a diagnostic done on my 2003 SEL after the Check Engine Light came on and was flashing. Car was idling/running really rough, and was losing power. The Engine codes showed misfire cyl. 1 & 5, rough idle below 1000 rpms, and lean fuel. I had a complete diagnostic done, and was told my ignition coil was bad. I changed the coil pack, plugs and wires, and mt car was running GREAT for about 4 hrs. Now I have the exact same symptoms as before I changed out the coil pack. Any ideas what could be going on??? Any known issues with coil packs or related items????
