Engine jerks while idle

[lhie]

Hey guys,

do you have any idea why engine jerks while idle? napansin ko na nag je-jerk ung engine once every 2-3 mins pag naka idle or nakahinto sya. sabi ng kapatid ko baka sa high tension wire daw. ano pa kaya pede i-check?

thanks!

Not enought info. Anyway, remove and check your motor mount.

posibleng misfiring yun maaring may problem sa electrical or timing lang

Timing, idle speed, high tension wires, lots of things electrical even the computer box. Fuel filter, fuel pump anything that may be clogged.

the best , ipasyal mo sa mechanic mo para ma diagnose maigi yan

agree ako sa iba. madaming reason yan. pero you can start with the items na pwedeng i-DIY at walang cost. like yung mga cleaning solutions lang. wala namang harm na magagawa e unless di ka talaga marunong.

by the way, what's your car or engine type? EFI or carb?

pero common fixes:
1. check high-tension wires for breaks/cracks or for loose connections (best to do it at night without lights. start the engine and observe the high-tension wires kung may tumatalsik na kuryente)
2. check/clean distributor cap and rotor
3. check/clean/re-gap/replace sparkplugs
4. replace/clean air filter
5. replace fuel filter
6. clean MAF sensor (for EFI)
7. clean carburetor
8. check/adjust timing

tama, check the ht wires for cracks. if meron replace them na.
