So I am recently separated and took the chance to pick up a 1987 S4 turbo! I had a RX8, but the soon to be ex gets to keep it. So i will tinker with this. It was basically stripped when I got it. Not running, no interior, you get the idea! I got it running really well with some new plugs and wires, new cooling fans, cleaned up the intake and new Corbeau racing seats. Then the ECU went bad, no spark, Injectors not firing, tried a new crank position sensor, didn't work, so I can only assume it is the ECU! Any other ideas?
