hi johnny, scotland can't be that bad for not even having supra specialists, have you check out that website? so you travel from fife to envy? thats miles away! well, my car's been playing up recently,jerking whilst driving,felt car's losing power, suspect engine misfire, it played up 2 days ago when its raining but drove fine today, start up fine when cold but after driving for a while, the problem starts. took it to Krypton Tune garage to run diagnostics, found comm port's not working, doesn't release any info to their system, tried going through manual bypass, doesn't work either.
can anyone help?
