Greetings all, Here's one I've not hear before. My 91 348ts is in for service/inspection. On the way to the dealer the car stalls at every stop light. Service discovers ECU's are fried. They get new ones, check them out on the computer, everything looks ok. Install them, take the car out, runs like a champ. Tech pulls up to a stop light, hits the turn signal, slow down light comes on immediately and one bank of cylinders shuts down. Gets back to the service department, and discovers that anytime the turn signal is activated OR the parking break is activiated slow down light comes on and bank of cylinders shuts down (not sure which bank). Service tech believes it's a short in the console somewhere and is trying to track. Anybody ever had this experience? Any suggestion on what else to try?
