So some of you might know, Ive been struggling with this truck on and off since I bought it. Smokes on cold start up and has a rough idle/miss until warmed up.
Contribution tests showed Cylinder 5 to be at 89% while all the others are around 100%. Ive put in a new ( good used) injectors and nothing changed. Same symptoms and same contribution results. Swapped injectors to different holes. Same thing.
I did wash the motor before before doing the injector job as there was crud everywhere so I wanted to make sure everything was clean.
After the injector swap/ Engine wash I started getting P0606 Codes :frown2:
Killtests didnt really prove anything. Today I tried doing the kill test by manually unhooking the injector wires from the injectors.
When I took the injector #5 wires off and did the contribution test there was only a slight change in the idle and contribution tests dropped to 88.
I then put it back and took the wires off #2 and the idle changed more and contribution numbers were reversed. #2 showed 88% and the rest were 102%, including #5????
The strange part of this was I was still able to do an injector kill test on the injector that had the wires disconnected. With #2 disconnected I killed every single injector in the software one by one and everyone changed the idle.. I was surely expecting the injector that had the wires disconnected to not react to the kill test software. :|
Im lost for words with this truck. Nothing makes sense with it.
I do have a compression tester coming in the mail tomorrow and that will show if I have a bad hole. But this P0606 has me worried about more $$$$$$
The code doesnt seem to show up until I touch the throttle then the check engine lights up. :frown2:
