If any one can help here. Replaced all six plugs but the #5 coil pac had oil on it. Had it replaced and New NGX plug installed but car seems to run fine but now car has slight rough idle when at stop and in gear. RPM bounces ever so slightly now. Never did this before. I'm going into dealer again but this jerk wants to sell me a new set of coil pacs but tech said the rest looked fine. Any help before they have there way. 2k2 70,000 miles!!!

 

Hey man! I got a 2002 with 70k as well .

Go to another dealer, it might be a rubber seal around the plug that is leaking...

 

How does the spark plugs look when it at 70K MI ? very worn, the tip are melted , still got life in it.

 

look burnt and worn at 70K going back Tom. to dealer to see if they can settle the idle down without getting taken. Any thoughts?
