Throttle position sensor/circuitry checking w/resp. to poor fuel econ.

[motogo1]

Well, on my TPS, voltage between pins 1 and 2 is 5V..in spec per Bentley.
Between pins 1 and 3, 1.6 volts. Not even close to Bentley spec. My car is
chipped with IA III+ and runs strong, with no problems. I'm going to have to
check the mileage, to see what I'm getting.
