Sorry.
My mistake.
I should have presented my car in firsth place...
It is an `88 supra, 3000 turbo engine, manual transmission, targa
I`ll post some pics to be more concludent:
This is all about the 2 leds above the ECONOMY, in the tachometer gauge.
In the supra handbook it says to try keep it into the green if u want economy of fuel. Mine doesn`t light up the green not even when idle...
And I managed the performance to go 250KM with a full tank...
So I was wondering if something is wrong, something that is affecting my car`s thirsth for gas...
