salam bro... my ride mengalami masalah lebih kurang macam hang la. cuma bezanya prob E30 aku... bila nak tarik or tengah speed tiba2 enjin macam CUTT-OFF dan kadang2 mati terus. penah sekali saya tengah speed kat hiway tetiba enjin mati. so, gelabah biawak jugak la nak lari dari lane kanan ke emergency lane. pastu kena tunggu dalam 10 - 15 minit baru bleh hidup. agak2 sama ka dengan problem bro shul kita ni? memang bikin hati runsing...

yours motronic or Ljet?
If L Jet, check your distributor rotor arm... mungkin haus ALSO please get new Fuel Pump Relay... This relay kekadang dah lama, so the current supply tak mencukupi. Cost new RM75

mine is motronic bro. rasanya... maybe la ada kaitan dengan ECU pasal saya punya alarm auto-lock. tiba2 satu hari tu enjin mati... alarm dengan central lock tiba2 out. terpaksa pakai kunci untuk bukak pintu. dah tu kena buka 1 per satu plak tu (kanan, kiri dan bonet). ada jalan untuk saya selesaikan masalah ni dak?

p/s: sori shul... terhijack thread. kebetulan prob lebih kurang.

Takpa line kelia chaq,sekurangnya aku tau jgk apa puncanya...problem kita lebih kurang sama chaq,cuma aku punya kes enjin mati time masuk/drop gear....bila time nak potong jadi camni mmg gelabah gila la,mmg dangerous!!!
Enjin aku Ljet,byk kemungkinan kalu jadi kes camni,kena check 1per1 yg mana disyorkan oleh sifu2 kita, takut jadi lbh kronik....lgpun membahayakan kita semasa memandu...

Hmm...bleh gak tu,klu ecu motoronic ngam bleh masuk dgn Ljet punya socket bleh la aku try....alternator dh check OK,skrg aku tgh test run after setting idle bg tinggi skit,sbb sblm ni idling agak low,klu still jadi jgk penyakit ni aku akn check another source plak,bila jd camni bkn senang nk detect apa punca sbnr,perlukan masa & kesabaran sbb penyakit misteri aku nih jarang berlaku....tp bila sekali berlaku sendiri mau ingat la!!!

Tetiba muncul plak si jeembo nih..hang hilang mana selama ni bro??senyap je tetiba muncul...camna hang punya projek e30 dh siap blum??kasi lansi la weh....
Btw thanks jeembo diatas suggestion2 hang,akan ku periksa satu per satu,bateri aku baru tukaq je,cable bateri pun semua baru....cuma valve cover ada leak skit,alternator ok,fuel pump aku blum check lg,vacuum problem pn bleh jadi gak sbb time aku start enjin,meter yg kat bwh rpm aku tuh mcm something je pergerakkannya...kejap naik kejap turun tak menentu...rasa2 mcm ada related je dgn penyakit misteri nih..

bro dah settle ke blum?
kereta aku pun ada masalah camtu gak...lepas check check ada wire sudah terbakar dekat kawasan mounting absober right side(driver side)
it's not actually a wire, but something like copper(kuprum) connector...
so,,copper tu dah terbakar skit... tinggal halus jer...
aku pun sambung kan terus (by pass) copper tu.. skang dah ok dah..
