when the spacer was on the throttle had a lag...and when you turn the truck off it made a crazy sucking noise immediately after the engine stopped.

when i took it out the throttle works like you would expect it to and the sucking noise doesnt happen anymore.

 

Sounds like there was a vacuum leak. That would explain the lag and the sucking sound when you shut it off. But, without seeing that setup, it may have been something else.

 

started a new thread with my 318 biuldup...took it to the track tonight...and i am STOKED!!!

 

I'm removing my TB spacer & lost the stock bolts. Does anyone know the dimensions of the 4 stock TB retaining bolts for a 1998 Ram/Magnum 5.9 ?
