For like 8months ago, When i didn’t use my car for 2-3 days. The car started stalling and shutdown on start. And it used to shutdown while driving. I went to mechanic, he cleaned the throttle body with an tissue without taking it off. And attached computer. It worked perfectly fine afterwards.
Now, Again. The car was not is use for 4 days. Today when i was driving it stalls constantly. I went to mechanic. He did same cleaned throttle body and attached computer. As i took the car out of workshop. it again stalled. Than idk what he did, he was like clean the oxygen sensor etc. Than i was sitting away. I heard extremely high revs like someone has unattached the Silencer. Than he called me and sai its fine now.
While driving back home, The rpm remain very high. However the car didnt stall.
Now what could be the real reason? And why is the rpm high than normal. If sometimes become normal too.
I want to know reasonand suggestion before visiting him.
Note: Car is Honda City 1.3 160K driven. And he also mentioned your car silencer needs cleaning. (Although the fuel economy is excellent, and there is no lack of power that i feel).
