Hello,
I have a Cultus 2016 model (EFI) and I have been having a problem with the RPM and the engine specially on idle. When idle (both during driving and after just starting), the RPM drops to about 600-700 and there's vibration and un-even engine idling. Like you can feel the car shaking slightly and engine isn't as smooth as it should be. As soon as I rev the engine, the vibration stops but while driving there is a subtle un-evenness (idk how to describe it) throughout. (Picture attached of the RPM needle, this is after driving for about ~20 mins)
I suspected it to be either an IAC or Throttle Body problem and took the car to two Suzuki service centers in Karachi. One of them didn't even acknowledge the problem while the other agreed with me and did some cleaning of the throttle body and informed me that the MAP sensor was not set. Still the problem has not solved and I'm really frustrated right now. Even took it to a local mechanic, he couldn't pinpoint the problem either.
Any suggestions what it could actually be? Thanks in advance.
