After my car warms up ('06 Elise) it has a continuous "squeal" or "whistle" coming from the throttle body area. It is annoying. The idle seems OK, maybe a little slow to drop, but the car is running fine. The noise goes away as RPM is increased.
Last night I was poking around at the vacuum hoses and spraying some no-residue contact cleaner on different spots without success. Finally, I sprayed close to the fuel rail and the idle changed. Repeat, same thing. Does this indicate a possible leaking o-ring at the injector? Would it suck in there without leaking fuel out?
One last question.... Might that give me a squealing throttle body, or is that probably unrelated?
