It is the sensor directly out front on the intake manifold. It is the coolant temperature sensor.

Hmmm...I do not have any codes or a check engine light though.

Thats right too, it would dump fuel, mine would leave me set until it cooled off a bit. And also, correct it did give me code, check engine light came on for a second, and then off, did not stay on, only when it missed and carried on. You have no engine code? If the light even blinked on and off it will leave a code.

No code, no light flashing. Just an occasional drop in idle when in gear waiting at a stoplight.
