Hey guys, I've done a lot of searching but just can't seem to find anything, so I've got a 98 2.8 GU which has got a bit of a hesitation down low when taking off from the lights etc, I've never noticed it out in the bush and once it's happened it revs out and runs quite well.
I've changed filters, checked maf etc nothing really seems to fix it, got me a bit stumped.
I've also noticed that it doesn't seem to happen when the tank is full, bit driving 100kms a day it doesn't stay like that for long
I've also noticed a puff of bluey black smoke when it happens.
The only things I haven't had the chance to check are the injector pump and injectors being that funds are a tad low atm

Does it happen once warmed up?

You say hesitation, but what is it like to drive in 1st at 700rpm (idle)?

Can you accelerate from 40km/h to 70 in 4th gear?

It does it cold and warmed up, and mainly in second but sometimes in first and third.
It's fine, happens only when I'm taking off.
I say hesitation because I don't really know what else to call it.
Yeah, sometimes it'll do it sometimes it won't,.
Hardest part is if it's not doing it it drives well

Is your balancer bolt tight?
Does it idle smoothly after a few big revs at standstill?
Or could be crap fuel unfortunately the list goes on and on.
Has it being doing it long ?

Is this hesitation for a split second not long after starting from cold and driving?

Cheers

Balancer bolt is tight, yeah idles fine.
It's been going on long enough to have gone through a few tanks and change of fuel filter. I always fill up at bigger stations with high turn overs

Nah, does it when warm and have been driving for a while as well just not quite as bad
