Hey guys, I'm having a difficult time figuring out a problem with my fuel Injectors.
I recently installed a set of Ksuspension 4 Port Injectors, they run fine 80% of the time but occasionally throw codes PO201-PO206 and I'll lose a cylinder or 2 at idle or under load then a few minutes or seconds later it's back on all 6. The odd thing is my stock OEM Injectors run perfectly fine all the time. I've inspected the wiring and I don't see any frays or bare wires.
This is my second set of 4 Ports that have done this so I'm confident its not failing Injectors.
Any input anyone has will be much appreciated, I'm knew to the Cherokee life.

 

If your stock injectors run fine, then it isn't the wiring, it's the injectors.

You probably have El Cheapo Chinese fakes.

 

Test the resistance of each injector and list them.

 

That's what I thought as well, but they're from Ksuspension. They're a pretty reputable brand.

 

Yeah, I'm gonna do that tomorrow. Just so odd to me why stock injectors work just fine

 

Depends on who you ask. There have been accusations that ksuspension is selling fake chinese 12-hole Bosch injectors.

 

I've never heard of Ksuspension before this thread, so I don't have any dog in this hunt.

All I know is, if your stock injectors run fine, then it isn't the wiring, it's the injectors. Don't let a reputation blind you to the obvious.
