its a diesel?????? a bit of smok is ok, esp on startup u will get some, n if u thrash it, shouldn't b that noticeable while idling...

put some diesel injesctor clean thru the tank, cld have dirty injectors or sumpthing....

ive ran injector cleaner the good stuff that you conect to fuel pump and its excessive smoke and only getting 200km per half tank city driving dont know were to start arb reckon the A/F is fine

Sounds like you may need new / serviced injectors.

Temporarily remove the airfilter, and see if there is a marked improvement, if so, get a new air filter. If not....... Carry on looking at fuel problems.

ive been logging fuel consumption since i bought the car bout 6 months ago, its done 250k and i get between 14l/100km to 16l/100km, depending on whos driving, if roof racks r on, n if its town driving... the woman seems to get better fuel consumption than me... go figure ?!?

99 2.8 gu BTW

Consider yourself lucky its black, not blue like mine :/

Has this problem just started or has it been like this since you bough the car?

asumming your injectors are in good conditions (hard to tell untill you get them removed) there is an adjustment on the injector pump which will allow you to adjust the fuel settings.
I dont know much more than that but i know its possible as i had mine adjusted as it was overfueling and blowing to much smoke after the injector pump and injectors were done.

You need to speak to a injector place and they will suggest the injectors first i would think.

Agreed, did my injectors a while back and made a massive difference to smoke

Toyota sent out a bulletin a few years ago that said when a customer complained about excessive smoke the first thing to do was to rev it about 20 times from idle to near max revs (parked and in neutral) to blow out any accumulated soot in the exhaust system & then check how much smoke it was blowing

Costs nothing to do and worth a try to see if it makes any difference
