I would imagine that the reaction time of the odd injector would be different due to the lower current through the coil due to the higher resistance, so while the injector may function it may well not function correctly, this could result in lean running on this cylinder.
I too would seek a replacement that matches the other 5.....

Thanks all. I was thinking they should me more or less the sameas well, just didnt know if those differences would be significant enough to cause issues. Will contact the supplier.

Try these in my 98 xj with very good results. I wrote a long story about my findings but lost it sorry.

Tell us more please Fisho.

A interesting find and a interesting read
