I own a '02 Esteem and the car is holding together pretty well even after covering 1.3L with almost everything in stock (even the clutch).

Lately I've been facing issues with idling during cold start( the first start of the day). Car does not stay idle during cold start for atleast 2 mins, After that i can release the accelerator and the rpm will be around 800 and the engine will be purring normally.
Throttle body is also cleaned during last service.

I've been thinking of taking the car back to service center but never got time.

Car behaves absolutely normal after the first start for the rest of the day.

What could be the problem??

I doubt if that's a problem by itself. I experience a similar thing with my Ikon, where on a cold start the RPM jumps to around 1.5k and then slowly settles down to a 800k mark within a few seconds.

The problem is, engine turns off due to lack of fuel going in. So once i crank the engine, I've to keep pumping the accelerator to keep the engine live for atleast 1 whole minute.

For MPFi engines it should be the other way around, as in the engine should run at 1.5K RPM for cold engine and should settle down to 800K RPM when it reaches the normal running temperature.

Your temp sensor might be weak or shot. ECU picks temperature of the coolant to detrmine the engine temperature. In cold starting your ecu does not understand that it is cold and fuels normally and your car behaves like a carb engine until it warms up.

Thanks knob for the reply .

Question: Is this temperature sensor is different from the idling sensor? or am i referring to the same thing?

Cheers!

Thats the bearing number - go to any parts shop and ask for a 6301 bearing they would give it to you . The maruti part number would be different.

I know what your car's problem is. I faced the same problem in my Zen that has covered almost the same mileage as yours.
Get the Butterfly Valve cleaned nicely by hand, NOT WITH A CARB SPRAY. This will solve your problem. Trust me.
It doesn't cost much, maybe a few hundred bucks.

Please do update after you get it done.

Take your car to MASS and ask them to run a scan, they will tell you which sensor is shot, first of all, all MPFI systems are closed loop systems and will through a error code if there is an issue with any sensor. if there is any issue the engine diagnostics light, same as technologists avtar will light up on the dash, and thats the signal for a malfunctioning sensor, and not because its not idling well. Take the car to MASS or to a workshop with a scan guage and it will point you in the right direction.

Also ask them to check/ clean your injectors.

Hmmm.. I'll ask the MASS to run a scan and I'll ask them to clean the injectors . My "engine check" light is working well though. I can see it coming up during the start up.

Unfortunately mine is not a CARB version brother. Thanks alot for the tip.

Engine check light coming up during the start is normal, the system runs a self diagnostic and if everything is fine the light goes off. do this tomorrow, start the car run for 10- 15 minutes without bliping the throttle and then turn off the car and disconnect the battery, leave the battery disconnected for 15-20 minutes and then reconnect the battery and start the car, see if the car is working fine.

My car also has the engine light issue and after a lot of experiments it turned out to be an issue with the front left passenger power window switch. If it is used along with the driver window, engine light comes on. Yes, the passenger window sticks, hence keep a can of wd40 in car. The light goes away after a couple engine on off.

LOL, who told you MPFis don't have a butterfly valve???

Hi,

I have 2007 Esteem VXi and so far covered 82k kms, recently i got it serviced for 80k kms at MASS.

1.Clutch cable was changed as it was hard.
2.Engine and Gear box oils changed and body rattling noise was fixed.

Mech says for next service Clutch plate and both the suspensions needs to be replaced. Want to know whether it is mandatory to replace suspension at 85k kms. Also want to know other maintanence i need to look into. Monthly i travell around 1500kms. I dont have any other issue with this car and i just love this.

regards,
Karumbaiah

Hi,

Three things come to mind which indicate that the suspension work needs to be done

1. The car is sitting down due to a sagging suspension.
2. The tyre uneven wear and tear is very important indicator if the suspension weak
3. Wheel alignment will be very difficult to sustain if the suspension is weak

Trips to Coorg could have taken a toll on the suspension over the years.

Cheers

My bad! Buttterfly valve DOES exist and the throttle position sensor is mounted on it. I'll get it cleaned "by hand" ;-)

I just mentioned that the orange light is working fine and it comes up during the start up. I would do a clean up of logs
