    Smile Slow throttle response

    Hi Fellow Vectra owners,

    Hope u can help. i have a 2007 sri vectra and noticed it has a very slight flat spot changing into 2nd and 3rd. Ive had it check out by fellow mechanic and there are no fault codes coming up...He said the throttle uses a fibre cable which sends a signal to the ecu rather than the good old faithful cable straight to the carb....Has anyone else suffered this prob or any ideas what i could do to make it run smoother....Ive used a fuel treatment incase of blocked injector but no difference......Ive herd the c max suffers too.(sorry for swearing) He He..hope u can HELP!.....

    Oh ist a 1.8 vvc engine 5 speed manual

    cheers
