Bradley, it has also been recommended to replace your old Main & Fuel system relays with NEW relays. They are both the same part number and are located above the ECU. I recently took one of my 89 SPGs off the road. I have swapped 4 or 5 different ECUs into this car to have the symptoms go away for a variable amount of time, sometimes hours, sometime months, only to have the problem come back. I have used these same ECUs in three other cars. One ECU does not work at all, two of the others have exhibited similar results in 2 of the 3 cars. I have another 89 SPG that has been trouble-free. I just bought an 89 900 turbo convertible.....
Good luck,
Jon
