hello frank thaks for your reply,it also has slight hesitation also, i know this is very common with a micra but its driving me bonkers,almost feels like the engine mounts are gone also. If you plod alonge say at about 2000revs and let throttle off an on its very all or nothing, seems like its to lazy in deciding how much fuel to put in. My voltage is the same as you said above, my O2 sensor seems to stay at 0.05 volts on tick over then when you snap the throttle it will dip to minus then to positive 7 to 8 and then keep flowing up and down between a volt for a couple of seconds then just stays back at 0.05 volts.  Is this normal?  I thought it should always flow on tick over between 1 and 7 approx.  I have adjusted the timing to all different settings but to no avail.  At slow speeds in very high gear uphill it won't miss at all.  It is the same cold as hot.  One thing I did notice is that my fuel pressure is 2.2 to 2.3 bar with vacuum pipe on.  I think it is meant to be 2.5.  Do you think 0.2 would make this happen?
