FAST EZ-EFI 2.0 Map Sensor

Hi Guys - My FAST EZ-EFI 2.0 system has been experiencing a rich idle condition for the past several months. During my last call with the FAST tech support guys, they recommended replacing the MAP sensor, which looks to be located on the front of the throttle body. I'm expecting the replacement Tuesday. My question is - has anyone ever replace a MAP sensor on their system, and how much disassembly is required to get to it? I'm hoping I don't have to remove the front fuel bowl to replace it.

Thanks as always!

Re: FAST EZ-EFI 2.0 Map Sensor

Hmm I don't see one that's obvious on Summits web site. My TBI system is similar and the IAC valve is broken and causes the unit to run rich. I found that out when I went back to a Holley carb for racing. To locate your Idle Air Control Valve, note the round hole located at the top of the air horn between the two rear barrels and you'll find the valve at the bottom.
