I have 1993 supra 3.0 non turbo (manual 5-spd), whilst driving at a steady 60 mph on the motorway, the warning triangle and engine management warning light illuminated, I immediately stopped, switched it off, then restarted and it was ok, but this repeated itself 3 times. following this, the engine cut out without any warning, with no warning lights. The fuel consumption prior to this fault was noticeably increased.
if anyone has any clues please let me know.

many thanks in advance smithen999 ;)

hey :)

have you done a diagnostic yet?

jumper te1 & e1 in the diagnostic box and switch ur ignition on and count the flashes

i would assume mk3 & mk4 are the same

try that and see what ya get and we'll work from there ;)

Hey,

Did this, and the engine management light flashes multiples of 4 - 2.

thanx. ;)

ok so it flashed like this?

flash, flash, flash, flash,,, flash, flash?

if so that's code 42 which is speed sensor signal, does ur speedo work?

yeah thats it. speedos working fine, it hasn't been converted to mph either.

i'm currently hooking up with some mk4 owners so shall have some good info for you soon :)

jump your supra into a dyno and c what happens. if u cant solve it get a pro that can

a dyno will not make any difference to the outcome of his problem...

also have you got a speed cut defencer in there?

what do you mean when you said you haven't converted it to mph yet? where in the world are you?

the dyno will allow u to go at high speeds so u can check if anything goes rong. its not 2 solve problems its 2 find them

please

he has a check engine light coming on and you suggest he goes and rapes it on a dyno :rolleyes:

if he has one of his speed sensors not connected properly or is not sending the required information vital signals are lost to the ecu and therefore dangerous things can happen
cel problems do not require high speeds or high throttle solutions
