i figured that seeing as i'm asking questions i might as well ask a couple.
my 4ag runs mega mega rich. i use about 10 litres of fuel for every 70 km. and when i put a piece of white paper to the tip of the exhaust with the car idling, after about 30 seconds there were heaps of little black dots on it and it stank of fuel .
i can smell fuel coming out of the exhaust all the time now, and i blows a fair bit of black smoke.
the motor has excellent compression on all cylinders and blows absolutely no blue smoke, but a heap of black.
is there a way that i could lean my mixtures out somehow?
without screwing with the computer?
any advice would be very much appreciated cos i'm about to go bankrupt just paying for fuel .
also--could running really really rich be the reason for a really bad hesitation every time i change gears?
