Saturday morning light came back on , got the appt. for monday ????

 

today is wed. they found 1 spark plug in # 7 cyl. that was fouled . I run platiums and this is the only one out of 16.

Will pick up the truck today and replace the plug on friday.
Se what happens next.?

 

Read a post a while back with same issue.It wasn't the plug going bad but the coil pack intermittently failing.Truck went in 3 times for fouled plug.

 

I am replacing both plugs on # 7 cyl. Then we will see , out of the items to check was the coil, hope they check that .

 

First, you changed the plugs 15,000 miles to late, and you used an after market plug. I am surprised they did it under warranty.
The manual specifically says 30,000 miles and copper plugs. Just for warranty sake, I will let them do the plugs in two years. I might be at 30,000 by then, maybe.

 

I have almost 40,000 miles original plugs still runs like it did new.

 

The 5.7 Hemi also uses a NGK Platinum.It is used in the Durango hybrid and one other Chrysler product. The part number will soon hit the part counters for 09/2010 trucks as well.As hot as these ignition systems are I find it hard to believe a plug fouled.The thread that I read on another forum that truck went in 3 times in two different dealers.3 times plug was fouled and replaced.Finally a tech got smart and realized it wasn't a plug issue but a coil pack or coil pack connector issue I forget which but that is what fixed it finally.Yours may be a plug issue but I'm skeptical.

 

Dodge came out with a addemdum on the 30,000 ... I can't recall what the mileage is now . I ck them at 30,000 and they look fine .

Our shop mech. help me replace the 2 plugs , cleared the comp. nd the light is off .
Will see what happens next ?

 

2 years 30,000 miles , you must be retired to drive 15,000 a yr. or live in a small state ...lol

 

I've read about this addendum on this forum but have yet to see it in print.Until its proven its 30k for me.
