Just rebuilt the ETA on my 1993 300CE. I'm sure the wiring was done correctly. Now I have a rough high idle (1500) and the ASR light is on. Is there any type of teach that has to be done before it starts working correctly?

Please fill out your profile so we can help more. If you do a search you might find the computer and ETA have a syncing process. Also build a code reader if you dont have a factory light installed to check for codes to lock down the issue.
