City 05 a/t car does not idle after starting, hard starting

[swmonsoon]

Good day po.

Asking for help here. My car wont idle immediately after starting and hard starts after few attempts of restarting.. Tapos kahapon nmatay engine nung i start at binuksan ac.

Cleaned throttle body, cleaned injectors, valve clearance, reset ecu at casa, ganun pa din po.

Tnx in advance

boss dapat pinacheck mo na rin sa casa. check mo rin IACV.

have you changed your spark plug na?

[swmonsoon]

IACV was adjusted at the casa

Spark plugs were ruled out,, since the casa guys used new spark plugs to trouble shoot. Ok nmn daw. Main relay was replaced 4 months ago kc nag hard start din sya and was immediately resolved by replacing the main relay.

Iba po this time eh, ayaw mag idle pagka start kaya namamatay, tapos ilang hard starts at attempts bago tumakbo ulit. Napansin ko, nangyayari to pag nakatakbo na sasakyan, pero sa umaga one click lng oks na.

Wat could possibly be causing poor idling and hard starting? Thanks

If lahat ng system used for proper of your fuel burning were checked and ok sabi nila, tiningnan na ba nila yung fuel distribution line mo?

Fuel pump, fuel filter, fuel filter sa tank (if meron) etc.

And nag ecu scan ba sila? Sa ganun na case mo, makikita naman nila sa ecu scan ang problema, kung saan may reading na hindi within tolerance then they can see the issue. Kung hindi sila gumamamit ng scanner na nakakabit sa pc monitor, then hit and miss ang ginawa sayo.

May software ang Honda na tinatawag na Honda TIS, ipa-scan mo ulit ang PC mo, hindi yung check engine light trouble code ang hanap mo dito but yung mga readings ng parameters ng sasakyan mo.

Sa Toyota parang ganito yan..

Sabi sa casa they performed ecu scan and wala daw sila nakita na problema, mahal ng binayad ko indi naman nasolusyunan ung problema.
They replaced the fuel filter few months ago, fuel pump is okay daw.


Thanks so much for the replies.
