Spark Plug Replacement? What is the final verdict???
#11
I know the car version of the eco differs a bit from the truck, but most of the issues are the same. Our lincoln was in for what felt like a miss and it was. The plugs were shot and they changed them to the updated ones and the paperwork noted the gap set at .28 per tsb. I assume there must be a tsb out there somewhere with new specs. The engine seems smoother and stronger then ever. We were at 68k were told to change at least every 50k from here on out and if a lot of city driving maybe every 30k would be better.
