Hey guys I'm in too. ... Anyone got a solution to the dancing rpm yet ? ... I thought the battery must be a issue but I changed didn't help. . . Can it be a faulty alternator ?
I tried some physics and checked the voltage ground on the engine bay while giving it a load there was a decrease in minute volts. But the same thing was happening while checking the voltage on the battery same thing happened less volts.
So in order to come to a conclusion guess what keep your car off and beem the lights see the fluctuation in the dome lights or try it with the indicators on dome light also blinks. Any one facing this too ?
Btw I have get the throttle body serviced professionally the problem got a bit ok but after a few kms the same thing happens my car is 25k driven only.
Waiting for a solution with you all.
