hey all, i have a mates 07 BF xr6t Auto that wants some work done but before i do anything i would like to work out an issue its having so im hoping that some1 on here has had the same issue.
ok soo it accelerates absolutely fine through 1st gear then up until around high mid-high rpm in 2nd or 3rd then it just stutters and wont make anymore power, then he'll back of to idle (stopped) and it idles rough, then he'll accelerate again it'll be sluggish and hesitant then all of a sudden it kicks back in and accelerates fine up until high mid-high rpm.
at first i thought it may have been the fuel pump on its way out so we replaced it with a walbro 255 today (no change) as he re-gapped plugs 1 month ago and done top coils 5 months ago.
any idea's fellas?
