for those who seen my last post will no doubt know I am new to Cosworth(saph 2wd) ownership. anyway, I have a slight concern, when driving the car and putting my foot down, the car pulls but seems to hesitate at say 3000-4000rpm and sometimes carries on until 5000rpm, I can hear the turbo winding up(excuse wording) so its not as if it isnt working. There are no signs of any smoke to indicate the turbo has gone, or no smoke to indicate the engine is at fault, no oil or water loss or anything. All I can say is the car is totally original, turbo engine the lot and has covered 66k....the odd time the car does pull very cleanly through out, does anyone know of any past experiences or faults it maybe...would appreciate your help.

Thanks

 

get some new plugs etc or go and get your car set up
