Help please, car runs great for 1 minute then begins to stutter then gets to 4000 rpm and runs great again until i change gear and below 4000 rpm.   I leave the car to get cold and it runs great but only for 1 minute.  Any ideas this is driving me nuts.  Changed plugs, leads, distributor, coolant sensor, dizzy cap, coil, air filter etc

thanks

Fuel starvation? Check the fuel filter and perhaps pump.
