Thanks a lot for the replies. I did made a search earlier and ended with the picture posted by medicine man.
But I have a problem with the terminologies used in the picture (that's why I was searching for the workshop manual instead)...
words/terminologies used in the picture diagram -like:
VSV, VCV, VTV, HIC, EGR-VM, Ch.B, BVSV, Canister, DP, V s/w, TVSV
Sorry I'm not really familiar with these and was hoping the workshop manual might have a better explanation for it/them - the picture did state that "See Repair Manual When you have any question"
