Spark plugs?

Are you able to drive your car eventually even though you cranked the engine and die off? Have you check whether battery connections are tightened? When was your last change of spark plugs? The problem can come from many things such as fuel pump, fuel filter, MAF (air flow sensor) and air filter, ignition coil/s, spark plugs, etc etc.... Any engine check light? What is the battery condition or CCA (cold cranking amperes/power) when you bought it? Did the battery shop show you any reading to show that the battery is fresh and/or in new condition? Otherwise, you have to go to workshop especially those shops with diagnostic equipment to check your car.

Btw, you can still start your car with dirty throttle body but just that the RPM especially idling is not very stable as carbon and dirt may have clogged the butterfly valve...

Hi

Yes manage to get it started after a few tries interval of 2-3mins. I have not changed the plugs, will do so asap together with my servicing.
Do you have any recommended workshop with all this diagnostic stuff?
Its been happening since last week, sometimes 2 days once, sometimes 3 days once.
This morning i manage to go to Point A (park and off engine). Then from Point A to B (park and off engine). From Point B that is where it start for half a second then dies off. Eventually manage to start it again.

The immediate thing you can do right now is to check your battery terminals for loose connection. As for those workshops with diagnostic equipment, my company has tied up with 4 of these workshops throughout Singapore to serve our 8000+ members/customers. Do let me know which area you are staying or working so that I can recommend you to the nearest workshop (in Autobay, Toh Guan, Ubi or Woodlands).

Can you let me know the address for Toh Guan and Woodlands?
What time does the Woodlands shop close on weekdays? Might just go today for change of plugs.
Who to look for?

Thanks

my car service by autosaver, the got run diagnostic and says everything okay.. that was 5k mileage ago.
now is 55k there about mileage..
battery is good condition, only maybe 1 year old.. engine cannot start is not cold state.. is hot state after maybe 50km and resting 10min... it cannot start.. only after 10-15 cranks then it starts..
wow, u state so many things must check ah.. u suggest tan chong or autosaver can do same job..

Denso FXE20HE11 cost $110/set, labour for plugs change various with workshop but cheapest would be freelance mechanic, around $30.
