I have a 2006 Suzuki Grand vitera 2.7 AT 36k miles(yes original Milage)
I am having the same issue as original poster. The idle bounces 1800-2000 rpm randomly. Sometimes it will be absolutely perfect, sometimes it would act up.
I could turn the car off and on 10 times and would act up half the time.
The car had a junkyard Throttle body on it(had part number) So someone changed it once before.
Cleaned the Throttle body on it, No fix
Purchased a used throttle, cleaned it. No fix
Installed New Accelerator pedal sensor. No fix.
I have the following codes
p1603 TCM trouble code detected
p2101 Throttle actuator control motor circuit range/performance
p1703 Can Invalid data from other ecu
c1075 steering angle sensor calibration incomplete.
I am starting to think it is the ecu, but am scared to purchase one and it not resolve anything.
