Also share range of such estimate

where is xulfiqar bhai?? no response in many days..

[zuhairz]

Dear Xulfiqar Bro.
I have a chvrolet Joy 2009 Model. which I bought second hand in 2013. at start the car had brand new tires(Chinese) and there was a very small deflection of car towards LEFT side and I ignored thinking being the problem of alignment and bought the car.
I had checked with Chevrolet motors muntgumry and many other good alignment mechanics but the problem has actually gone worse with the passage of time n I have to hold the steering all the time or the car deflects towards left (more prominent in high speed)
People are actually unable to find the root cause and some says Camber issue som say spring issue and some says tires issue(already changed v less improvement) No major wear n tear on tire due to alignment issue

Can you suggest any thing to look for?

@xulfiqar can we use Caltex Texmatic 1888 as power steering fluid in Nissan QG engines?

Is it okay to use air con with the heater ?

@xulfiqar @naweed @syncview

Aoa experts :
Vitz, 2011 model, 60,000km
Its running at higher RPM than normal. Its Throttle Value was cleaned 1 weeks ago with Liqui Moly Throttle Value cleaner. (simply by removing intake hose, without removing throttle)
After cleaning, when started, its Rpm was higher than the normal.
Mechanic suggested to disconnect battery terminal to reset ECU and than start engine and run it for 5 to 10 minutes in idle. But after doing this, same problem remains.
Then he said drive car for 3 to 4 days, it will be adjusted automatically. But after running car for 400km in one week, same issue. Any suggestion or advice?

Check if the connection to IACV (idle control valve is loose). Problem seem to be related to iacv or some vacuum pipe

Dear Zaman,

Just mere cleaning of throttle body by removing air intake and spraying wouldn't help much. You will need to get throttle body dismantled and have it serviced properly. This issue arises due to IACV (Idle Air Control Valve). It's loose connection also causes the same problem or if the valve does not move freely in its chamber (or is sticky), the air intake is not normal which leads to higher or lower RPM. It may also fluctuate RPM because of this.

Try having it serviced through some good workshop. Do remember not every Tom Dick and Harry can do this job properly (as I have had this experience with my City) so do select a good or reputed workshop

[Naweed]

IACV usually is a stepper motor .. advancing or retarding accelerator linkage as per requirement .. just reinstall its connector nothing more .. sometimes static charge of body can damage such sensitive part so do not open ... and check vacuum pipes .. throttle body should not be opened and cleaned unless something is really indicating its malfunction

@arzaam.bhatti what if i use it constantly?I have a friend who does that. In winters, air set to hot and a/c turned on full time.

[capsat]

you means AC ON - or the Blower Fan
-
randomly using aircon in winters keep it functional and cooling remains stable when winter is over.

USING Heater while AIRCON engaged ..does not make sense, the heater core is circulating water from HOT engine while Aircon compressor is doing its job circulating refrigerant in the evaporator unit [ cooling coil ]

please verify from your friend,

I have been in his car, last winter he used to put the a/c button ON while the temperature set to the warmer side in his vitz. The temperature did felt much nicer to me as opposed to using simple fan.

Thanks brothers, will check these and share my experience with you guys

like capsat said it doesnt make sense to use heater and Ac together all the time, I can understand maybe it will be more comfortable if you are on the borderline between white and red as the cool air would mix with slightly hot air however if you are any more further in the red then it doesnt make sense, then its just shortening AC life and getting worse fuel economy without benefit, howvever winters it is still smart to use AC once in a while as it keeps everything in good shape especially the seals lubricated, AC should always be used now and then whatever the weather to keep it in good shape but using it with full heater all the time would be a wastage.

Beautifully clarified. Will let my friend know about this.

AOA sir hope you are doing well, i have a question that after the auto gearbox of my car which went bad so i converted it into manual cultus 3 cyl engine gearbox in my charade, the gear makes noise in 1st gear like shhhhh then if i shift it into 2nd then this noise goes off and if the car is sitting idle(neutral and engine started) karr karr karr type of sound comes from it until i press clutch, it actually loads engine as rpm fluctuates and sound of engine changes as i leave clutch. (all gears work fine)
this karr karr type of sound is so annoying, i pored in PSO gear oil maybe GL4 or 5 (2.4 L)
even that auto gearbox worked smooth for years until its gone my bad as i poured in the wrong oil in that auto gear, i still miss that auto gear...

[Xulfiqar]

@arzaam.bhatti - your benz also runs the A/C with heater - other than the cooling function, it also has one important job which is dehumidifying. wet hot air is not a nice experience in a car, partly dry warm air is always welcome.
