Which sensor/mechanism controls the drop of rpm when acclerator is pressed and released? I mean the rpm is supposed to come down to idle slowly, which sensor makes it to come down slowly? Is it also IAC valve?

IAC's job is just to control the engine idle rpm. When you rev the car, more air + fuel mixture is pumped into the combustion chamber as the throttle opens up and as a result, the engine rpm goes up. When you take your foot off from the accelerator, throttle closes and the engine returns to the idle rpm. If your engine's rpm does not come down quickly enough then you might have a leak somewhere in your intake manifold gasket or a pipe going to the intake manifold could be leaky. Have you checked the error codes (if any)? If you state your problem in detail then may be we can help you out better.

no i havnt checked the error codes yet. problem is the rpm falls rapidly to idle when foot is taken off the accelerator whereas i think it should come down just a little slow.

Hi Friends,
My Liana LXI is although performing very well on CNG and Petrol but what i m noticing is it needs some Shimmering job as i have drivin 15k KMs and in total it has done 60k KMs. Question is

IS SHIM JOB VERY PRECISION WORK ?
I MUST VISIT SUZUKI 3S FOR JOB ?
MY MECHANIC IS VERY GOOD IN FIXING JDM AND HI TECH CARS HE SAID ITS PIECES OF CAKE FOR HIM!

I m very much scared that after shim job may b car start missing or something else goes bad, cox its running perfectly fine its just it has some shim sound on giving hard accelerator on low RPM.

please suggest

Shim should be inspected every 40k km
Shim job is like
Remove cam
Remove all 16 shims
Measure thickness with vernier caliper
Throw the one which are out of required thickness
Removing cam on m13a is not easy as not every one can reach timing chain tensioner

Saboor bhai whats wrong with shims if we grind them like Khrad Wala people did in diesel engines (I have experience of that) and engine Become in its original tune.
I meant to ask why it's necessary to put new shim as we can use same shim in some cases.

Yes seen that happening you can grind shim one time only ppl tend to grind valve tip as well grinding shim gives more clearance but it better to get them changed

what is the cost of one shim? and how would we know if shims need some servicing/replacement or not?

Shims are cheap as chips on Toyota engine you can see buckets for the very same purpose which are expensive as hell

To check shim measure there thickness with vernier caliper

shim starts from 400 PKR and car retaliate on giving accelerator on low RPM(pehly ghotegi then utegi and you will feel engine vibration) , tappet sound in engine room, low picup, RPM drop down on idle

oh then i think i need to get my liana's shims checked. cuz car does retaliate a little bit on lower rpm. where you from? are you planning to get your car's shims checked?

This is how shim work is done.

i checked a 3S dealer in karachi who seems to b very skill full person and what ever he told he had valid justification for that. I m from KHI

When I turn on ignition switch, from last 2 days the lights in Cng swich are remain off , while lights in metre become on , but when I start the car Cng switch lights become on as usual.
But before this when I turned on ignition key, (before starting) lights become on both sides that is metre and Cng switch both.
But what happen now ? Any help or suggestion ?

If you go to the 3S, they will check gaps, remove shims, mark them for new measurements and then send them over to the Kahraadiya for grinding. If you get new shims from 3S, each shim costs somewhere from 400 upwards. Most 3S don't have those in stock.

[bilalawan774]

This is how shim work is done.

means this job will let you change to look at fuel injectors and clean them ,, tell me what precautions should i need to take.

Don't mess with injectors if there's no need. 3S have no proper equipment to service those. You will get into more trouble.

My car in parking of uni - taken today

[abid110]

Today had my cars ac serviced. Cabin filter changed, blowers throwing more air now. Gas topped to full. The ac on off button in the panel was not working. I was asked to make it direct with the blower (middle wala round). So, the electrician did it, now when we open the blower, ac turns on. Performance is good. Today was extremelyyyy hot in khi and it performed adequately.
