Bumalik na lang ako sa bahay at di na ako umalis baka kasi itirik ako. Ano po kaya ang problema? rotor head po kaya? (sana hindi naman). Possible kaya na injection pump? How about yung nozzle tip? Nagreplace kasi ako ng nozzle tip almost a month ago na, mausok at malakas sa diesel kasi before but after mapalitan yung nozzle tip, nawala yung usok, tumipid din sa diesel pero hindi nagbago ang batak. By the way, nakita ko naman po kung paano ni-replace yung nozzle tip, maayos at same code din yung pinalit, zexel po yung brand.

Ride ko po, 97 Isuzu TFR 4JA1

Thanks

Try checking everything external like valve clearances, blocked air intake system. etc. But from experience, this seems to be an injection pump problem.... more specifically... the rotor head.

Good luck.

Dieseldude,

Salamat po sa reply sir, pa-check ko na lang po yung injection pump ko next week. Sana di naman gaano kalaki ang damage.

ooops!!!! sorry po sir.... na excite lang ako kaya natanong ko sa inyo.

sir, how about yung magnetic sensor na kinakabit sa injection pump for RPM? nakita ko po kasi 2wires siya.... isang black and isang red w/ black. alin po kaya yung sa positive and papuntang gauge? and yung papunta sa positive kailangan po ba sa ignition ang tap or direct sa battery mismo? maraming salamat po ulit....

sir dieseldude question uli.. (stupid question)

nag stock ako ng petron diesel last month (early december).. then nung isinalin ko kahapon sa clear container napansin ko iba na color nya.. from greenish naging yellowish...

pwede ko pa ba gamitin? sayang kasi kung itatapon 40liters din yun.. sa L300fb ko na lang ikakarga kung pwede pa...

maraming salamat!
