the ECU regulates the fuel delivery dependent on the coolant temperature, it sounds there may be a problem with it. is there a Fuel Cut Defender wired in or something similar? if not you might consider getting a second ECU to try it.

The car is bog standered just has a jazzy air filter. i tried an ecu but its the same i'll try another cool temp sensor in case my one is faulty thanks a mill cause my heads melted from it
