I have Suzuki Cultus AGS 2018. Bought this car about 1 a half year ago. Whenever I got its throttle washed, its RPM goes rocket high (1500 ~2000 in idle condition) and it used to come down after 2 to 3 months time.
I got this examined from multiple workshops even with Suzuki Dealerships, but they could not identify correct issue. Every time I take this issue with any workshop they just say its throttle issue and they wash throttle but issue persists. I feel like its taking air from somewhere or may be something else.
Any help/guidance will be appreciated.
