Got a 2002 dodge intrepid, 2.7 engine, and 6 cylinder. Coil 4 is misfiring. Change spark plugs and coil and its still misfiring and saying on the computer that its coil 4.|||can't fix coils. one replaces them just like you did.
from what i see in the http://www.autozone.com/autozone/ manual, you need to check power source to the coil. test for issues in the pcm harness or pcm itself.
