Problem Reports

I have replaced 2 of the 6 and now another one has gone bad.

Ignition coils have been a continued source or aggravation on this vehicle, so far have replaced 3 of 6. Fortunately 2 have been on front of engine easily accessible, 3rd required removal of intake manifold (not complicated, but time consuming).

Starting at 60,000 miles I have had a misfire code for one of the coils on plug (V6) every 20,000 miles or so. At 75,000 miles I had another one that I drove too much before repairing and it plugged up the Catalytic Converter - you'll know because the car will be slow on acceleration and very poor on fuel economy - 80,000 mile warranty, but the dealer will fight you on it since the exhaust manifold integrates three catalytic converters and the job runs the risk of fouling the muffler also.

I have replaced 5/6 coils and all spark plugs twice. This last time I did the job myself and did not go OEM on the COP - wait and see. It has been a $600 dollar job at the shop - if the coil is in the front - DIY - If in the back - consider paying the mechanic as it is more time consuming and really requires a haynes or chilton manual to do it right.
