A bad injector will most likely not throw a code unless it is absolutely awful. I had four injectors gone-the truck would hardly drive and it didn't set a code. You probably have already checked the basics but:
Fuel pressure, injector contribution balance, ficm main voltage. Then more in depth is pull the valve covers and check for high pressure oil leaks. Another trick is if the miss is at idle you can disconnect the icp pigtail and see if it changes. That will force it to a default setting. You may have a bad icp sensor.
Is the miss consistent? Only when it's cold? Only at idle? Sorry for being disjointed-im tired...
It's cool lol
To check everything you said, what all would I need? I could get the livewire up and running soon, but for contrib wouldn't I need a AE or something?
It's mostly at idle(that I noticed) and while I was backing into a parking spot, it started jumping a little, then later it had a shake while it was idling. I rev'd it to 12, 15 and 2k rpms and I didn't notice it.
It's doing it hot.
I'll try to check for HPO leaks this weekend and the ICP sensor.
