it's ok up to 2000rpm, and it's ok after about 2750rpm, but in that band it hesitates and stutters when it's cruising.
it's fine when it's pulling through that range, and its fine over running down through it, but trying to hold, say 2200rpm, it's uncomfortable. it doesn't kangaroo, or wallaby, but it's getting slowly worse.
i assume that it is a sensor somewhere needing cleaning or replacing, and i do need to get the valve cover off and clean the gunk out (only 'cos i haven't done that since i got the car yet) and i will replace the hoses at the same time.
i've run injector cleaner through it and put a new (k&n) filter in. no difference.
anybody got any suggestions of where to start? (and no, buying a redtop is not an option 'cos i got no cash)
