Hi Sir Diesel Dude thanks for the reply.

Nalimutan ko banggitin that the fuel filter has been replaced as well. Good.

The scan was made at our suking servitek and if i remeber correctly yung brand ng scanner nila was coincidentally innova din. Never heard of an Innova scan tool.

IACV and EGR are still in their original form. No repairs done yet. Did servitek assure you that fixing the IACV & EGR will correct the problem?

Still have to check the fuel supply pump and bleed the fuel lines. You can bleed the fuel supply lines to the pump. I don't suggest that you check the supply pump if you don't have the proper training and tools......... danger due to extremely high fuel pressures. Leave this to the experts.
There are days upon start up it will idle straight away but then there are also those when the symptoms re-appear. On normal driving everything seems to be ok no rough idling, no engine cutting out never pa naman tumirik or nag stop yung engine. This is a possible fuel supply pump problem.

Many thanks You're welcome.
