Sorry for the delays.. comcast strikes again. Using the functional test at
idle in drive, selecting "tcc enable solenoid" it does kill the eng. On
test drive, using the same function, tcc does apply when turned on by
scanner...  Tcc on the scanner is showing tcc enable and pwm ramping up,
but no rpm drop. It does not set a code.
