Hi fellas/gals.... Can anyone beat the High tecs? Here's my problem.... my 1995 gtr started to cough a bit while travelling along, likr it had a slight misfire. it didn't do this on acceleration. left it into Nissan Peterborough and after 5 hours of Diagnostic, they found only very minor issues. They replaced fuel filter, some air intake valve. No engine light ever came on except on ignition. they tried 1 suspect coil, but problem still remained, my timing was out by two teeth, so they say. then they said it maybe a faulty igniton amp. so after paying 675 to get my car back WORSE because it then started to have the cough/misfire fault on acceleration too.???!! so i changed the coil pack beacuse they said it was common for 2 coils to go down. I bought 6 second hand coil packs and the car ran much much better, actually better than it ever did but now the slight cough still remains while driving normally. Could it be possible for the ignition amp and coils to be gone at the smae time?? my car is as it left the factory zero mods and they tec said he has never seen one with so little issues. so can anyone shed some light and beat the high tec???? is there anyone in the peterborough area that can let me try out their ignition amp? a tank of fuel for anyone who can do this. Thanks for listening to the ramblings of a fellow gtr owner. Joe number is 07 508 608 708 if you can help on the ignition amp test.
