White smoke and backfiring under high rpm.
 

I recently installed new injectors, everything works great except when the rpms get up, the truck runs really choppy and it blows white smoke. Runs really crappy when its cold too. I let it warm up for about 15 min and that barely helps. After I installed the injectors, I bled them twice to get the air out. Is it possible that more air bubbles stayed in the system? Could it be a timing issue? I upgraded to Bosch 370s, the only other upgrades are my KN intake and 6" straight pipe. Everything else (to my knowledge is stock)

does it settle out after the motor warms up? what is your timing currently set to?

Yeah, I does settle but it usually takes awhile. While it's hot, if I really romp on the accelerator I get a little white smoke. I haven't figured out the timing yet, I'll have to get back on that.

its gonna be timing related .. to far advanced .. when you install bigger injectors you add timing as the new "bigger" injectors can input more fuel sooner in degrees of rotation ...

so ... I would pin time the IP and try that .. once you have that straight ... adjust from there. :tu:

Thank you very much, I'll get err' done!!
