I have a stock b16 with stock injectors and walbro 255 fuel pump. The engine Idles fine and there are no CEL's running stock p28 that worked fine on another car. What happens is if ease the throttle open it runs fine. But if I press the throttle too fast or if I crack the throttle just a litte it bogs and shuts off and I can see a little white cloud of smoke in the intake manifold.

Any help would be great

 

Update: I cleaned throttle body and now only thing it is doing once you rev the motor when returns back down to idle it wants to stall.

 

Is there an idle adjustment anywhere on the throttle body? Is it loosing air or fuel?

 

had this issue on my gsr. turned out to bemy iacv.

 

not sure if it is loosing any,there is an idle adjustment. the idle right now is between 700-900

 

I will check and clean it and see what happens

 

Cleaned IACV did nothing
switched out IACV that did nothing

I moved the throttle stop up and it got rid of the bogging issue.

 

So its running good now?? No more bogging?

 

maybe the throttle positioning sensor?
i had this problem, but it was a d series engine..i had it narrowed down to the tps and the iacv
