Hello all, I ran a CCT test with AE because I thought it was running rough and got a cylinder #4 balance/ cylinder contribution fault. I have both valve covers off now and #4 is not spitting any oil. I just found the IDM pinout and will get the ohm #'s for all the injectors. Any ideas?

 

Check the UVCH to that injector and if that's good swap the solenoid with the one next to it and see if the issue follows the solenoid

 

Ok, I'll do the swap next, Uvch looks and texts good. I ohm'd all the injectors at the IDM plug and they all said 3.0 Ohms.

 

i pulled 2 solenoids off and notice on the one that wasn't spitting oil that the spacer deal the solenoid sits on is turned 180 from where the other solenoid's is. Is that a problem?

 

No, doesn't make a difference on the spacer under the coil. I had to ask that question myself a while back. I got the same code from a CCT with AE the other night. Same injector. Mine wasn't oiling like the others. They are premium built Rosewoods, just put in so I knew it wasn't the injector. Changed the harness for those two cylinders with another used harness, and it's oiling better and no codes on the CCT.

 

So did that fix your miss again Bill?

 

^ x2 I've been wondering about your miss, bill, as I suspect mine may be something similar, but I haven't dug into it yet. I did replace all my UVCH's when I did my GPs last time though and it didn't change anything. i'll have to remember the injector solenoid swap test if it comes to that...

 

Nope. I'll have all new Ford ones tomorrow. See what that does. I doubt that's my problem though.

 

I thought you already changed the harness's Bill?

 

Two sets of Dormans. Just doing the Ford ones for piece of mind.
