2000 Chrysler Concorde 6 cyl Wheel Drive Type unknown Automatic 110000 miles
Car idles fine most of the time but all of a sudden the rev counter increases from 600 to 1300 and settles down again. Can feel hesitation while driving too. Car stalled twice while stopped at traffic light.
Engine code says Ignition Coil Secondary. So, I bought a new coil pack and swapped it with each individual cylinder. The problem remained no matter what. Have done a tune up (air filter, plugs, PCV etc). Any help will be appreciated.
