My 2003 vw passat v6 was recently installed with a new coil pack wires and sparks it ran great for 1000 miles now it runs rough i noticed that the coil has a 1 2 3 6 4 5 sequence when standing in front of the vehicle it appears different from the firing order is it wired wrong

Check the following...Vacume lines, warm up valve, frequency valve, o-ring injectors and the actual injector,fuse box pins and the fuses, loose fuel relay, ground wire from battery, all wires to and from the coil. test the coil for function( if you have a strong steady flashing pulse on a timing gun, its good). Be sure you check the entire Digifant Electrical system from the Halls sender on the distributor to the TCI module on the fire wall of the car. It sits on top of the Brain( That would be your ECCS unit......short for electronic computer command system!

A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.
