Swapping to a later ('89+) intake doesn't eliminate the IACV. It's just integrated into the throttle body, much less complicated. I have done the intake swap on mine, and I recently had to replace the IACV with a new one ($OUCH$), the old one was way out of adjustment and not working properly, but it only affects the idle.

Daniel, if you need an older reed-style IACV, I still have one.
Did you ever get that Tuffy console mounted?
