    Show us a datalog of the IAC issue if it's convenient for you to replicate it. We may see what is driving the issue. Also as a test, cover the throttle body with tinfoil and ride past your store front to try and replicate the issue.

    It'll be the end of the week before I have time to cruise again. I could put a layer of foil tape on the underside of the hood, but it would look like crap and might cause a fire.

    Use your imagination. It's only for a test, so as long as you don't interfere with any moving parts (throttle linkage) just do the best you can to cover the throttle body with tin foil. Looks like you could use the filter base as an anchor point and let it hang like a skirt from the base of the filter. You could wrap it around the throttle body and when you get to the throttle linkage, squeeze the foil together some as to not interfere with the linkage.

    I ordered faraday copper fabric that blocks EMF/EMI. I'll wrap it in that.

    EE stands for "Electronic Engineer" or "Electrical Engineer"?

    Everything Sniper and fuel pump related is grounded to the battery with its own separate wires. Battery to starter. Battery to frame. Frame to block. All good wires with new ends, soldered and heat shrunk. There's no way to ground the hood, fenders or firewall. It's all press molded composite fiberglass.

    I could run a second ground straight from the block to the battery I guess? All my gauges are grounded to the block. I could move those to the frame.

    An old AM radio on a quiet station may help you find the source. Look up Ferrite RFI suppressors. I don't know about cell phones, but portable walkie talkie radios can cause RFI if you're close to them. Holley told me the sensor and main harness wiring was all shielded if that was so an outside source should not effect anything. Heck if that was the case all of our late model cars would cut up when we rode by Walmart. Only thing that effects mine is a damn gas station...it pulls in on its own.
