Rob,
do you have these in for 1990 GTO TT? MOT wednesday next week, the one i have is a little lazy, so may or may not get through on emissions, so of course may or may not need one in a hurry 
Simon
i have two for sale from my 96 3000gt not sure if it will do the job for ya?
paul
Wrong type, 3000gt sensors do not fit a GTO and in all honesty the only place for second hand lambda sensors is in the bin. They have a usable life-span of about two years.
Mark.
