Well I did bubble test and didn't see any. Runs pretty smooth when cold but gets worse when warm. Guess would hurt to go ahead and check them.

Would it probably be a good idea to go ahead and pull out the injector harness and open it up and take a closer look at it? I took the harness out when replacing HPOP.

Ok good They should be 4 ohms or less so 0.8ohm is Good

The Coils also should be Open to Each Other


You can also check the Harness for continuity and should Load Test #7 harness

Well I pulled my harness and the #7 plug has crimp connectors on it under the cover and tape. Is that factory or someone before me jacking with it?

it could be having issues in either spot

I havent pulled mine apart yet but would think somebody fixed it at the crimp connectors does it look like it rubs something there

Pretty good Odds your Harness is the Issue

Take a DVM check for continuity threw those 4 wires even wiggle it around during the test so if you Lose continuity

crimp connectors are spawn of the devil. they can be ok if you have one of the compound crimping tools and you use the heat shrink crimp terminals. my personal choice is soldier and heat shrink. i have opened up too much stuff only to see the wires pull right out of the crappy crimp just by finger pressure.

I went and head and replaced the crimp connectors with the ones that have the heat shrink with them. I also repaired a couple spots that had split insulation. Seems to run better. Still getting a miss fire count on the number 7. Number 5 wasnt acting up today. Cleared my codes and still getting the contribution on 5. Will check later on for more codes. Also still getting blue smoke from the exhaust. My CCV is throwing lots of oil into the intake which I never had a problem with before.
