    Default Confused, suzuki swift idling issue?

    While driving late at night, I usually speed upto a 110km/h and then switch gear to neutral and slowly let friction slow me down. What happened last weekend was that the idle rpm fell to 350 and the car engine shut off. I started the car again and all was good. Since then I've been noticing that this is happening randomly. Sometimes 8 times in a single day. Sometimes not once in three days. On the third day when this first happened my check engine light came on, but went away after a few hours. Also whenever the check engine light is on I feel the car is getting a bit sluggish. Recently this has increased as well.

    Anyway, I've already refreshed my ecu via showroom. Also I've looked at the maintenance file at home and know for a fact that engine oil was changed 6k ago , ( liquimoly so usually change at 12k ), oil filter air filter and ac filter were all changed recently. Plugs were changed 1500km ago. Throttle body was serviced 2500 km ago.
    I usually understand whatever issue is being faced before going to any mechanic or showroom. This thread is for that exact purpose, so please advice.
    48000 km on the odo.

    I think even when the engine light was on the scanner was not showing any current issue in the section of powertrain. ( think that's the wrong word ).

    Then i use to drove it with check light on and suddenly one day it gets stop tried each and everything but failed
    Well then a senior mechanic of 3s visited my home where my car was parked and then he come to know that it was immoblizer issue
    And he did something in engine bay for half an hour and from that day no any check engine light or shut of ALHAMDOLILLAH so in short also check the immoblizer and check
    Insert key in ignition switch
    On the switch (where all light shows in meter) and check if immoblizer light is blinking or stable if blinking there is some issue

    The immobolizer is not blinking. Hey Id keep driving it too but the sluggish behaviour impacts driving pleasure so to say.

    And when the car shuts up during neutral and I need to make a turn, that could get ugly.

    Throttle body needs service.
    Money differs from an automobile or mistress in being equally important to those who have it and those who do not.

    Sir I was referring to the absence of immobolizer sign blinking. No cng, only petrol. ( normally mix high octane and petrol equally. )

    when they scanned it they must have been stored DTCs under that heading, one should not clear or refresh before noting the codes, next time check light comes on get it scanned again, did suzuki use a generic scanning machine or their own? as suzuki in-depth diagnostics will tell you about any deep issue inside.

    there must be some sensor thats chasing the check light to illuminate, throttle body service is not required and in fact should never be done except in extreme circumstances.
    If everything is coming your way, you're in the wrong lane!

    throttle body doesn't need servicing very often if using genuine air filter servicing throttle body very often could messup it sensors
