Hello I have a 1995 lesabre with the dreaded transition ecu I believe this is a computer issue but want to make sure so what happened was when I bought the car as soon as we signed the title over I went to the AutoZone across the road crank sensor went in their parking lot any who earlier this year the car would intermittently start came down to the ecu I replaced the ecu now the car does start every time you crank the key for about 20 seconds then starts and idles fine for 20 seconds then stumbles and sounds like it advances timing until it stalls but starts right up once you turn the key I can’t scan it because some jubilant head completely switched the wiring for the dlc connector
