I have a issue with my Cultus 2017 model old shape

[ahmad8146]

I have a problem kindly guide me so that matter can be resolved.is there any issue in if I advance the distributor.because due to advance the distributor the car runs smoothly on acc.while on normal distributor condition means genuine condition the car retards on long route.throttle body serviced .

[brownrose78]

Do u drive on petrol or cng or both?

Does your car rpm increases after switching on A/C

[ahmad8146]

Rpm slightly change.

[ahmad8146]

Drive only on petrol.

Go to any mechanic and ask him to tell your ignition timing on idle condition. In normal condition it should be 6 to 7 degrees. If its not this than may be some body has fiddled with timing belt and timing has been advanced or retarded by some unskilled technician.

[ahmad8146]

Idle on ac is on 800 rpm .can we increase rpm of ac.if yes kindly guide me how I can ac rpm.and also tell me the mechanic in multan.so that I can check my car ignition timing.

[naveedyu]

800 is bit low rpm with for carbi cultus with ac on howeverits good for idle rpm with no load connected. If you stand in from of your car then on right side under air cleaner cover and carburetor you will find an actuator for ac idle up. As some one to switch on ac when you look toward actuator it will move the plunger and increase the rpm. Tightening it screw will increase ac rpm. Tight it till your rpm are 1000 to 1100. Make sure all vacume line are intact as this actuat works on engine vacuum. If there is no vacuum line connected then it will not work .

[RehanBhatti]

For your kind information he has an efi cultus.

[RehanBhatti]

Your idle air control valve sensor adjustment is out. That sensor is attached on idle control valve which is located under the throttle body. There will be 2 mounting screws of that sensor, loose them and rotate the sensor clock wise a little bit, tight screws after that and check your rpm with AC ON, which suppose to be 950-1050.

[ahmad8146]

Rehan shb can you send me pic of that part.

[margallar]

on efi cultus , you need a good scan tool to adjust timing

[ahmad8146]

Sir in Multan can you tell me the workshop which has a Cultus computer.

[margallar]

I am not familiar with multan, but suzuki dealerships have the scan tool.

The problem is, most of them don't know how to use it

[ahmad8146]

I will check my car from Suzuki authorize dealer

[margallar]

the timing is "locked" by the scan tool, and then it is adjusted to factory setting, from the distributor.

[ahmad8146]

Sir if we manually advance the distributor then will it create problem for engine.
And secondly in Indus Corolla there is vaccum solenoid to increase acc rpm.is there any solenoid in Suzuki Cultus.

[margallar]

there is an option in suzuki scan tool for setting the timing, you enable it first and then you are supposed to adjust from distributor with a timing gun.

This is the correct way to do it.

No there is no such thing in cultus, most efi cars don't have it, they use the IAC in the throttle body for it

[RehanBhatti]

Tomorrow,I will send you factory service manual pic in which its decribed how to set ignition timing without scan tool.

[ahmad8146]

Thanks sir
