humina hatak after injector cleaning

Diesel calibrators will always tune an engine for a particular output. I think they calibrated you current air / fuel ratio would be on the lean side to prevent smoke belching. This however can lead to loss of power. Just bring it back and complain about the loss of power on your vehicle so they can fix it. Why did you have your injectors cleaned? Were you smoke belching?

Subok na yang dalawa na yan dito tsikot.

im from davao po. i had the nozzle tips balance due to higher FC. yup, ibalik ko sa gumawa ito. baka nga nasobrahan ng sakal ang tips. delikado sa opem hiway, lalo na pag mag overtake. kinakapos talaga.

sa crosswind na matic kadalasan nagyayari ganyan pag linis ng injectors humihina hatak. Sa manual tranny hindi. I had mine cleaned 5x already di naman nagbago hatak.
Sa cleaning ng injection nozzles(at least sa Zexels ng 4JA1) di naman magagalaw ang nozzle pressure unless magbawas or magdagdag ng shims. And usually sa cleaning nililinis lang talaga.
Usually sa mga matic na nagpalinis at nawalan ng hatak , ang ginagawa is inaadjust ang fuel regulating screw sa likod ng IP...giving it more diesel sa startup pressure ng nozzles.
You can also have your TPS checked

ok lang yan sir, ibig sabihin yung 90km/hr ang balansyadong takbo niya, yung dating 130km/hr hindi balanse yun

may downside din kasi ang mabagal, delikado sa open hiway. anyway, i observed na medyo nag improve ang hatak noong naadjust ang fuel enrichment screw sa injection pump. though not the same power it used to be, ok na ako dito.

baka nagkapalipalit pwesto ng injectors mo. ipa coding mo uli

i'm kidding on my last post sir

dapat ipaayos mo ulit sa gumawa at maibalik niya sa dating setting ang injectors mo para bumalik din ang dating hatak at bilis. sana cleaning lang pinagawa mo sir and no need for balancing. minsan kasi we try to fix things kahit di naman sira hoping that we can squeeze more power sa engines natin but in the end we're doing more harm than good. in your case, you suffer loss of power and torque...

Dapat linisin, palitan yung mga seals, tapos i-bench test yan para makita yung "flow" kung balance ang output ng kada injector. Kung di yan ginawa ng mekaniko mo, hula-hula lang yan. Di ka sigurado kung may leak or barado ang isa kahit na nalinis.

Tama rin na pa-check ang TPS (throttle position sensor), kung meron ka man nyan. Kasi ayan din ang magbibigay ng tamang values sa ECU para sa exacto ang fuel delivery depende sa values ng MAF. Para kasing nag lean-out yung fuel delivery at 90kph.
