my 93 has just come back to life after a lot of hard work and time....
the car has sat for about 2 years in a heated garage... and there was a reason...
after getting all the wiring fixed from the botched battery relocation the idiot that had the car before me did...... the car turns over and seems in decent enough shape...
except when its running it idles at 19k and backfires (not loud just little bubble like backfire and like every few seconds..) then when it gets to running temp... 87c it turns off suddenly and everything stays on just like nothing happened ... just the motor cuts off.....

any ideas... im stumped....
car has hks ic, greddy intake, apexi power fc, ss catback,
