Okay i'll start from the beginning, post referring to the lb7 in my sig. the other night i was driving about a mile from my shop where i was headed, i did a wide open pull from 30mph to around 90mph (top of fourth). everything seemed fine truck felt good like it always does, i came to a stop sign about half a mile after i did the pull and the truck was idling very rough and smoking white pretty bad from the exhaust. i was only about 500ft from my shop so i eased it on there. when i got there i cut it off and checked everything, the only codes that were present was a p0341, i immediately thought of injectors so i hooked up my v2 and started to check the balance rates and they were all at 0.00, no readings what so ever. So i replaced the cam sensor with a OEM from the dealer with no change.

I also checked the reluctor wheel through the crank sensor hole and it seems to be in tact and tight.


Now its also throwing a p0727 TCM code and it will not go into any gears from idle.


What am i missing?

thanks in advanced:eek:
