Before this problem occured, I complained at that concerned Isuzu dealer, during my 35k pm, a loss of "sibat" power during overtakings, they pressumed it was a clogged air filter, I have no idea if they done something on my auv with this complain.

By the way, i have noticed that in that particular Isuzu dealer, as shown in the job service sheet, DELVAC engine oil was used instead of the Isuzu Genuine Motor Oil (IGMO) and. "Mobil" brand for hub grease, diffrential oil, and power sterring fluid were used. They also put additives in the engine oil and diesel fuel. Is this a correct practice? I don't know. But I don't think this will cause low power. Try refuelling with fresh diesel fuel..... no additives.

I am going to bring my auv in a different Isuzu dealer somewhere in Makati, though i live in quezon city. I bought that crosswind in a dealer in south metro manila and pms there until its 20k. However, when I transferred in qc, for praticality I started bringing my auv in that particular Isuzu dealer in quezon city, which I think has a low quality services. How is the condition of your clutch?.........shifting ok?....... no slippage?

More power to you Dieseldude. Thank you.
You're absolutely right Dieseldue, the culprit was my fuel filter. It was replaced today and the jerkings on any rpm gone, smooth acceleration and the loss of sibat power during overtaking improved. Had i not consulted with your first baka ano anong troubles pa ihula ng mga taga casa instead of a simple fuel replacement costing lower of P400 and 30 mins to replace. I just asked the service advisor of that isuzu dealer to replace lang the fuel filter, mo more no less.

But still the problem was that the fuel replacement was not performed during the 40k pms which should have been done in accordance with the pms schedule. Hayyyyy... sometimes owners must be aware of those things and of those little maintenance negligence that will make a much bigger trouble.

MABUHAY KA DIESELDUDE... you'r damn good.
