Engine Performance problem
2002 Ford Excursion
Hello, first-time user here. I thought I'd try a little mileage-improving gizmo I found on eBay. It looks like a small resistor, and it's supposed to go between the 2 wires that otherwise would connect to the intake air temperature (IAT) gauge. The directions say to look for a small, 2-wire plug on or near the intake manifold. They also talk about what to do if you find a plug with "four or five" wires.
Naturally, my situation doesn't match either of these. I found one 3-wire plug attached to the throttle area that has a gray wire with a red stripe, a gray or green wire with a white stripe, and a brown wire with a white stripe, in that order. There is also a 6-wire plug (more of a large rubber stopper, actually) on the air filter housing with the following wires, in order:
Gray with white stripe
Black with white stripe
Orange with blue stripe
Blue with red stripe
(Note: the wires are all pretty dusty, so I can't be 100% sure of these colors.)
Any idea which of these wires are the two IAT wires?
p.S. FWIW, the gizmo comes from Innovated Engineering of Clearwater, Florida.
have the same problem?
