guys,need some help here
it have been a period after i notice the little changes of my car,i tot it will just goes back to normal but it doesn't.
here goes the RPM first,i have serviced my car,changing engine oil(semi) n filter,den it goes smooth,after that,i notice one thing,when i driving on the road,i brake,usually the car RPM slowly goes down right?but my RPM goes down,and stuck there,like from 3000,to 2000,den jam at 2000,when i completely stop,it will drop till about 1500,den it slowly goes down,down by 100,100,den bellow the level of normal RPM,sumtimes when i wait at the traffic light,the RPM drop till 600-700...
ok,here come the aircon part,the aircon will suddenly turn warm after i wait at the traffic light,even i turn on and off the aircon,i don't heard the compressor sound kicks.but after the traffic light turn green and i start moving,i press on the pedal n when car goes fast over 2k RPM,the compressor kicks again.but it doesn't works when i rev while the car is not moving.and sometimes,the compressor takes up alot RPM,when i stop the car,and the compressor kicks randomly,the RPM from 1.1/1k turns up to 1.5k den slowly comes down again to bellow 1,or even lower.
my car is waja 04,4g18,auto,anyone have any idea wat is going on?engine timing problem??how come the RPM is not stable one.
sounds like a plain dirty throttle body to me. Aircond cuts off when it goes down below 700rpm? ECU senses heavy load so aircond is cut off. And u may or may not need sensor recalibrationing.
