Dave did you run a new ground on Both wires? D1 and D3? Sounds like you missed D3 the first time and your fix finally grounded the D3 ground, the ambient override sensor ground.
Randy there is no Black ground wire from the dash thru the firewall to the bell housing. It is Black with a white...

What is the idle test limit on rpm in AZ? Here in Nev it is 1200 rpm. My car also fails at 550 but passes under load. I instructed the tech to 'high' idle the car during the test to the allowable limit. He ran it at 1150 rpm for the idle test and it passed no problem. I also...

Let us know how it turns out.
