Does an error in the secondary air system produce a rough idle/misfire only at cold start (around 1 min)?
The pump is running but what I get is error code 2760 Secondary air system-Air flow too low and some misfire codes on different cylinders each time.
engine is 100% perfect after the cold start, no stored errors efter the cold start (I erase them by INPA).
Thanks for any help!
