426ci stroker with a BBK throttle body and a Procharger.
This thing has a random runaway idle that I cannot get in line. Changes to the throttle body model have no affect on it. This car is a nightmare in every way! I attached the original tune it came in with also. I think it has been to a few places!
Have you tried swapping back to the stock throttle body and seeing if the issue persist?
I do not have that here, the customer says the throttle body has been on there for years and was never a problem before.
was the procharger already on there? or is that new?Originally Posted by hellbents10
It was on there before. Engine went from stock to a 426 with a cam, phase limiter, and MDS delete.
