tQ myshimra.. haha.. guaLa abang c AP3_3927

kpada smua geng2 SIoLOON n OTAI.. d bahagian chasis sy ada bka topic baru.. mcm karangan uda sy buat hehe.. masalah ni sR ga.. haha.. tolong2la p bca n solve 2 problm..

oya.. sy mau tnya kpada myshimra@yg berpngalaman.. enjin 1kz ni.. paling ngamla pakai pa pnya gerbox slain gearbox ori.. manyak susa mau cri gearbox ori o..

gear ratio utk 5th bagi hilux lbh krg 0.85:1, jadi try modify tu giginya gear 5th sehingga dpt yg kurang sikit 0.75:1...silap2 boleh abis tu jarum dlm 4000 rpm.
boleh jg tukar Differential Gear kepada Ratio yg lebih rendah dgn menukar gigi gear tapi akn mengakibatkn bacaan speedo meter tak betul...

ko try kasi adjust itu fuel pump...

Hmmm... standard ori 1KZ fuel pump taboleh adjust.... its ECU controlled.... Kalu mau tune, kena add performance chip. Price around RM1.8K d kk lah.... ada itu piggy back chip baru buli tune...

Oooo.... So itu 1KZ-T instead of 1KZ-TE lah kan.... Memang bagus tu mechanical fuel pump system... mostly geng 1KZ-TE yg hangkang fuel pump pun convert p mechanical punya kan.... sinang lagi cerita... tp, sa ada problem....

Im on 1KZ-TE.... Masuk p Surf.... Suma satu set + Auto Gbox.... Symptom, RPM time idling and cruising tidak stabil... turun naik dr 0.9 - 1.3.... Normally, lepas cuci kreta, dia jadi begitu.... air maybe from the scoop bonet depan or mana² ja lah kali... tp, normally, lepas sehari dua, rpm stable balik....

But last 2 weeks, lepas ujan lebat sama banjir d kelombong, RPM jadi gila²... sekarang mau masuk 2 minggu suda... turun naik 0.9-1.3... cuci intercooler baru² mmg ada minyak... tp masi lagi sot².... buka pasang balik semua sensor plug pun masi lagi... reset ECU (Buka battery sama cabut ECD relay and fuse utk beberapa jam) pun inda mau baik²..... last week jalan p kemabong dari kk, sepanjang jalan time cruising, buli rasa tu rpm turun naik....

Dimana yg perlu sa check kalau begitu? mekanik sa bingung² suda.... Kalau sa p UMW, memang kana sipak barangkali pasal recond punya kreta.... any help?

tmpt sy pun g2.. mekanik ckp mslah rpm melumpat2 ni slalunya dri fuel pump.. lupa da pa brg dlm fuel pump mekanik 2 ckp... lama sua bha.. mlas mo bikin sbab mekanik ckp x pa2 juga. lagi pun bleh bkin tpi klu diesel engine and psal fuel pump ni mmg sakit poket klu mo service atau bongkar... hehe.. bungkar sikit ja pun $$ kluar berabis..

Oooo... tp tpt ko mungkin inda begitu teruk? sa punya betul² irritating nih... Pernah dulu sa kana gini lebih seminggu, pastu sa hilang idea, boring² cuci intercooler and piping, buka throttle body cuci pakai carb cleaner, pastu pasang balik, reset ECU (Buka battery), problem rpm jump hilang..... but last week, sa test cuci intercooler (macam turbo leak or breather punya minyak), reset ECU, inda pula baik² penyakit dia... but d differrence is, sa inda cuci throttle body tu time.... maybe sa try cuci lagi throttle body and report any outcome... if problem solved, bye² breather hose.... sa kasi turun p bawah tu.... ada juga pakai oil catch tank, tp sama juga wap minyak masi ada... owh, mau tanya, EGR korang block pakai plate atau cabut vacum hose ja? sa punya masi berpasang...

pkai plate bro.. up sikit gmbr enjin bro??? hehe..
