2000 1.0L 16V Rough running

Hello all
my micra seems to run rough when its warmed up like it is missing:( and it is a bit thirsty on petrol

After doing all the basics like a service etc
I have had 2...yes 2 recon mafs on it to try and resolve the issue.
I had it scanned for fault codes and they said there was none

However its still remains a problem. Im in the process of replacing the exhust as the back box and centre pipe is fubard!!! So am going to check the condition of the cat cconvertors while I am under there.

Having looked on the net, people are sugguesting changing the temp sensor,
Would that be the coolant or ecu temp sensor on my model?

If so where is it located?

Any help to resolved this issue would be brilliant

Thanks
Dave
 
hi dave, there are 2 sensors on the N/S end of the head, the small one signals the gauge and the bigger (blue on the coilpack engines) one signals the ecu
