Vitz RPM drop at D, R gear

Complete service of throttle body including iddle control valve

[sohelahmed]

I had done complete service of throttle body from G 8 markaz, Asif EFI electrician, i dont know if he did any thing with the iddle control valvle, he just cleaned throttle body, plugs etc. Can you give me more details into valve kind of stuff.

thank you again for quick info...

[salmanrasheedpsh]

Also clean ur fuel filter or replace it

[hash4u]

If the throttle body was taken out n serviced.he should hv take out the iac valve n serviced it as well.i think he skipped that part

[sohelahmed]

i think so....i will chekc with another guy...

[sohelahmed]

i was coming from lahore last week, abs sensor ws not working , my mech told me that i was runing car above 120 in 4th gear, coz if abs sensores are not working, 5th gear wont shift....

can this be a reason of problem in d mode...

[hash4u]

Ur car is cvt
It has no gear changes like conventional auto gear
Kindly switch ur mechanics
Abs sensor issue has nothing to do with iddling

[sohelahmed]

i will visit mech tomorrow, currently my gas again leaked, when i turn on ac, it puts too much load on enginee, ride gets hard even when i switch off ac, i have to swithc off car then turn ok, which makes it ok. the problem is when i turn on ac, my rpm drops in d mode....

[sohelahmed]

can u also suggest mechanic...

[hash4u]

For AC visit abu bakar in isb.....just search his name on pw's his address n number would come up
For mechanical issue see zahid in enercon aabpara pso pump

If you have got the throttle body serviced and all that, make sure that the recommended spark plugs gap is 1.00 mm to 1.1 mm.
In addition ask your mechanic to perform the following calibrations with a diagnostic computer:
- Zero point calibration.
- CVT oil pressure calibration ( If it is CVT equipped car).
- Sensor G and Yaw rate sensor calibration.
Hope that works.

[sohelahmed]

here is the issue that was diagnosed after visiting abu bakar, and lots of efi electricians.

My AC compressor is jam which when turned on causes load on engine due to which it vibrates and shakes. When AC Is off, there is not vibration. Abu baker told me that i would need to change compressor, condensor if needed and vales etc. expecting 20K.

[hash4u]

He told u max amount....worst case scenario
Sad part is ....alot of summers is still left

the most important bit.

the throttle body relearn....

@sohelahmed

what engine and trans does your car have? - does it have the 1.3 corolla engine

[sohelahmed]

yes sir, it has cvt and 1.3 xli/gli engine...

[Xulfiqar]

what is the idling rpm when in gear?

[sohelahmed]

i dont know actually, i am checking with samandar khan efi electrician in sddar, he checks on computer, so far its diagnosed that its not rpm issue, it only occurs when i turn on ac which is faulty, my compressor is faulty, its jammed, i need to replace it. otherwise car runs ok

[Xulfiqar]

connect any scan tool and see the rpm at idle when in gear.

[nawaza]

Visit Enercon in G-10 those guys are the best with vitz get your car checked from them and your problems will be solved.

[sohelahmed]

ok i will check...
