Could replace engine coolant temp sensor . If faulty it can send a false signal to the computer and throw off the fuel and timing calculations. This will cause the computer to think the engine is cold, even when it is not, and as a result will over richen to compensate . Could also check / clean MAF if not .

I have changed the engine temp sensor , but it is still the same so my next move is to try the MAF . when it is running it is using much more fuel than normal .
