Change Fuel Injector Plugs?
I’m in the middle of doing a supercharger and camshaft install and when I took the injector plugs off, I noticed 4 of the 8 plugs were discolored. I don’t have any engine codes and no misfires before the install. Is this normal or should I be replacing these bad ones?
If needing to be changed, anyone have a part number? Thanks!!

I would make sure the pins inside the connectors aren't spread a bit from someone shoving something in there to testing for something. Looks to me like there is excessive resistance on that connection causing it to get hot. Meaning the pin is not making a tight contact with the male side.

Ive seen this before. Its fairly normal. Some discoloration on those ends wont hurt anything

Thanks for the input. If I have any fuel issues down the road, I will know where to look first.

pretty typical I wouldn't worry about it.

Hi. I had same discoloring. I had p0202 and p0302 when WOT intermittently. I had new injector, new spark plug, and changed coil to another one. Still same. Just look at the injector conector and saw that. And sprayed some wd-40. After that it runs good. I will try today to. I hope its all good.
