When i turn my city 2000 AC car rpm drop as it starting to shake this is happening when my car is on CNG but on petrol car doesn't start to shake but rpm remain same as it should go up after turning on the AC . Before going to a mechanic please any body can tell me whats the issue so that mechanic couldn't miss guide me and take more money as i pre know that..
Seems to be a cng setting only. At max kit service should fix it..if apart from rpm ur car cruises fine on cng.sometimes when kit diaphragm gets hard or cracked then idling becomes an issue...
i think u need to adjust gas to air ratio on on cng
Thnx for your kind response , One mechanic was telling me to ke aap ke throttle body ke neechy sensor se wo khrb hogya hai , thnk god you save my money , any good CNG service shop can u suggest me
Bro wo iacv valve hotaa hai..but if petrol is ok..then all is ok. Are u from Lahore? If yes then u can goto AutoMania in township or if u live near chauburgi..then whole market is there.. anyways..for other cities..some other bhai can confirm you
i am from karachi
Then...i know nothing:)
