I have all of these in stock
are you sure that the coils have gone bad?
that's an expensive way to diagnose the problem
have you checked the plug boots for carbon tracking?
have you swapped the modules from coil pack to coil pack?
there's other things to check also, but I would hope that another forum members have been helping you diagnose this
Thanks for the prices I have pulled all 8 plugs and they defenitely have seen better days... I know ignition coils/modules lose power/amps as they age due to heat, current, etc... I know when I used to do a tuneup on my SBC and BBC, I always replaced the plugs, wires, cap&rotor, and I would change the coil every 3-5 years depending on how many miles I put on it... I wasnt sure if the Northstar recommended that the coils be changed ever X amount of miles... Its nothing major enough to through a computer code but I am positive that every once in a while it is missing/skipping at times and I know the plugs could be the culprit but I was wondering if it was a waste of money to replace the coils... The car is a 2002 DTS with 97,000 miles...
