vehicle 1997 dakota engine 3.9L w/auto
The vehicle exhibits an intermittent high idle. I have replaced the usual IAC stepper motor and checked the tps for proper function, also completely cleaned, inspected and relubed the throttle body and linkage.
According to my Inova 3140, there are no codes and the temperature sensors and tps percentage are reading correctly. Also the battery and charging system are functioning correctly.
I do not have bi directional capability or the ability to monitor any of the pid’s
One other thing is that she also has a slight rough idle, but that could be the 200,000 miles.
