Try cleaning the line and little filter to the MAP sensor.


Mick

Pretty sure none of the 1KZs ever had a map sensor... The sensor your talking about would be the boost sensor and the what looks like a filter is actually a one way valve... Older engines that have a bit of blow-by can get oil into this valve and block it so then the ecu dosnt know its on boost . Believe me youl know if this isn't working there gutless without it !!!!

Hi Jason
around 145 l doesnt matter whether im towing or not
no roof basket only wider 265 tyres
what model is yours
cheers John

Sorry John, only just saw this.
Mine is a 2001 KZJ95R Auto
That consumption you quoted is approx 16.2 L/100kms
Does seem a bit high. I get quite a difference when towing, but one of the vans i have is an old block of flats aerodynamically.
Drove from Sydney to Coffs Harbour over Christmas with the van on & averaged 20 L/100kms on the way up.
Made a conscious effort to cruise it on the way gome & did 15.2 L/100kms.
Without a van i can do around 10.6 on the open road.

Regards, Jason.
