Can only one ignition coil obviously broken be replaced with one other used white top ignition coil?


#2

Spell check would be good here !!!

Front and rear coil packs are the same. Color is different since you see front coil pack. That’s all.


#4

My question was just whether single coils out of a pack could be replaced with a working used coil of the same type from another pack, without loss of performance over replacing the entire pack.


#5

It looks like they are individual coils sold as a complete bank of 4 or individually, you should be able to move the single coils around, they don’t appear to be unique.

10-4 and a great thank you Nevada_545. I had seen written that each entire bank would have to be replaced because of computer programming issues. I will find out for sure soon. Fuel economy is at 13.5mpg and rising after swapping out physically broken coil #4 from under EGR valve frame.
