Lly vibration at idle..

[Fastorange]

I have a vibration at idle on my lly.. the vibration goes away with rpm.. my guess is it is a bad injector.. the whole checking balance rates thing kinda throws me off... everything is between .5 -1.5 ...but the thing i dont understand is the fuel rate is 4 or 5... it should be around 9... i did replace the injector in cylinder.. and it seemed to help a bit.. i am using efi live to check the balance rates.. anyone have any input..

Check your balancer..... May have sheared the pin

The vibration is at idle, when you pull up to a stop sign you notice it.. but the truck seems to drive and run fine.. i believe the trans is going out or at least the convertor... i have read posts where guys had a bad clutch made the truck vibrate.. ill look at the balancer tomorrow...
