2008 scudo (tw200 taxi) the driver that was working the cab last night parked it up after the car started stuttering in 3rd and 4th gear , it seems to be pulling ok then its like as if a ht lead has tracked and you get some stuttering , car has has 3 clutches and flywheels in the last year...the last 1 being last week

is it possible it could have been caused by driving through a puddle? water in the alternator or something like that

any help would be appreciated

thanks
Andy
