Assalam o alaikum every one ... I have Honda city Vario 2004 model It's having an issue of dropping the rpm to 500 when the car AC is turned on and the engine starts to vibrate very badly .... The rpm drops very little when the ac is off but when AC is on feels like the cars engine is going to shut down ... Also this problem occurs when the transmission is on D S R or L. As soon as I shift my car to P or N it works fine.Engine tuning done, computerized rpm check done but the problem is still occuring ... If somebody has faced the same problem or knows about this situation kindly reply
just clean the IACV valve located below the throttle body clean it then give it a drop or two of lube so it may move freely also do the idle relearn processbtw tell about the coils sparkplugs and engine oil usnig
Was facing kind of the same issue with my exi prosmatec. In my case, its just some wiring. Currently I'm having the shockers replaced. If the wire moves from its place, the car starts missing with AC on.
Don't know about the coils and spark plugs bought the car about 6 months ago ... My mechanic said coils n plugs are fine. And I'm using shell 10w40 oil ... Will give it a try for IACV valve u are tellingThe only problem is vibration with AC on Otherwise the car is working totally fine
Will give it a try Thanks for your concern
yes brother i have the same car at home clean the iacv valve and do the idle relearn
