So I throw a CEL tonight. I go home and hook my predator up and it tells me I have an intake manifod runner stuck open, as well as misfire on startup. Please tell me what the nmanifold runner stuck open thing means. I had a BBK TB put on 2 months ago and the car has had intermittent episodes of running like it's hauling a cattle trailer. What do I need to do other than put my TB back to stock, or does the runer have anything to do with the TB?

 

did you get a new tune when you put on the throttle body? if not, i bet that's the problem.

 

Without knowing the exact code but based on what you have descibed it to be. This is an issue with the Plates located inside the intake manifold. Have you installed the Charge Motion Delete plates? If so did you tune it for them? If not then most likely the bladesare getting stuck or are not opeing or closing

I had stage 3 comp cams installed the same time as the throttle body. In answer to your question, I still have charge motion plates. Have not done delete yet.

 

Then you most likley have an issue with them internally. Time for a trip to the dealer if you still have your warranty.
