IAC
TPS
MAP
Snuck another question in on me. MAP sensor is on a bracket right above the passenger side valve cover.
I know the TPS is on the passenger side of the TBI unit itself, 3 wires, I can see it on your bottom photo. The wires go up towards the breather assembly. I have the Holley TBI as well, and the TPS was bad on the brand new unit. Now I think I'm fighting dirty gas tanks since the fuel filter looked so nasty.
First I gotta fix a valve cover though before I can keep trying on my TBI. I'm very close though to yanking off the new Holley and putting the stock TBI back on. I got the same intake, but a 350 with more ponies, and my mechanics are saying it is throwing way too much fuel compared to the stock TBI, running very rich all the time.
