audi a4 2005.. bad idle till warm... just had 8 exhaust valves replaced as cam belt broke and everything seems to be ok now except... on cold start idle is very rough .. however after ten minutes and warmed up runs perfect... anything I should check? heard so many different causes its confusing me
A rough idle that cures when engine warms could be a bad cold start injector or throttle position sensor. Could be defects in ignition from coils to plugs, or dirty injectors or clogged filters. Maybe you just need an extensive tune-up.
