Engine dies during idling - Team-BHP

mithun · 18th January 2008, 06:49

My Pulsar 150 v2 which had run about 27,500 KMS dies during the idling stage. I had adjusted the idle screw a number of times and the cold idle RPM is 1000-1100.

The bike was running without any problems and it's for the 1st time this kind of problem is surfacing. No adjustments was done to the bike prior to this headache.

Because of this, it's a pain to ride in the city and the engine always shuts off at slow speeds and I've to apply the throttle often.

help....

You might want to check and correct the carb tuning or clean the carb. Check and clean the sparkplug(s).

This also could occur due to an air leak at the intake side. And also a weak compression could cause this.

why not increase compression by facing off 1mm

help....

have you tried the time tested sure fire solution?

that is....

take it to an authorised mechanic!

ITS a ver very common problem. go to the authorised service station, clean carb + air fileter. check the air intake pipe for leakages. ask them to set the air screw on the carb. the process should be with engine tachometer and the CO testing machine. rest all he will do it. the rpm should be constant with perfect air scre setting and CO should be in the range specified. ranges from lean to rich mixture.
then test drive.when engine is hot it shouldnt die in idling.

One of my friend who owns a P180 DTSi used to face this problem when the bike was parked in hot sun for a long time. The mechanic said that it is due to the petrol getting evaporated in the fuel lines due to heat. Is it true?

get the air filter and the carb checked..
should solve this probelm.

I'm started facing this problem yesterday with my maruti zen after driving through some heavy Bangalore traffic.

The engine just shut down. I started it and it kept going but I heard a sputtering sound(kind of like when you're trying to climb a slope on 3rd gear at low speed) esp on 1st and 2nd gears. I had to press the accelerator little more that usual to take off.

After that, every time I took my leg of the accelerator, the engine shut down. I had to restart 6-7 times and drive like this back home. I'm planning to get the car serviced now(I haven't got it looked at for a year maybe since I bought it. I really don't want to spend too much on the car as it's 10 yrs old.)

Can anyone enlighten me as to what the problem could be. I plan to get it serviced at UM cars, Airport Road, Bangalore. Anyone have an idea of the cost involved?

The car must have carburetor rather than a MPFI. If that is the case then you need to get the carburetor cleaned and tuned properly.

humyum · 3rd February 2008, 19:20

Check the vaccume pipe that goes in the carburator?is it broken?Seems like a solenoid which controls the idling rpm is jammed.This solenoid words through vaccume pressure.
And since this problem suddenly cropped up i think the above mentioned thing is the problem.
Opening it and cleaning it with Wd40 should solve the problem.

alankarmotor · 3rd February 2008, 19:45

PLEASE FIRST CHECK WHETHER YOUR ENGINE IS OVER HEATING.IF YES RECTIFY,BECAUSE THIS PROBELEM WHICH U ARE MENTIONING IS ACOMPANIED BY SPUTTERING SOUND.NOW IF THIS IS NOT THE CASE THEN U HAVE TO FIRST CLARIFY WHETHER IT IS A CARB. OR A MPFI.

Yeah, what he said. But also look to see if the clamps connecting the hose are loose or missing and check the vacuum pipe for cracks and holes.

Jaggu · 3rd February 2008, 22:06

get complete cleaning and tuning done, since its 1 year since you serviced it

TDR · 3rd February 2008, 22:50

I had this problem with my Alto MKIII "aka Zen" (EU version with MPFI).
The engine just kept shutting down when idle.

In my case, it was a vacuum leak, like DirtyDan mentioned. Pretty easy
to fix. Did not find it easy to diagnose, though.. but then again, I'm not
a mechanic.
