Very new to this site and Micra's! I have passed this site a few times so I thought it's definitely worth joining. I was given a little 1994 1.0 16v Micra a while a go. It's been a great car, I'm more used to Citroen, BMW and Honda so the Micra was a little different but surprisingly good car to run and own. Anyway, this past week it's developed a problem, I'm 60% sure I know what it could be but would rather ask people with the right knowledge before I dive in with test meters etc. The car was driving fine, did a 100 mile round trip with no problems but on the way home my son said he could smell burning and his actual words were "it smells like dog poo" I couldn't personally smell anything so decided it must of been outside somewhere. The following day I started the car and it was running very lumpy, fuel economy suddenly went downhill and it stalled a couple of times as I slowed at junctions. This got me thinking of possible AMF sensor, coolant temp sensor or lambda sensor. I went out and checked the AMF with a test meter and it was .05 volts less than recommended so I brushed it off as working. Then the car decided to start and run fine again for a day, then suddenly go back to running lumpy etc again today so that has made me come and made my first post to see if there's anything else I should check? About a month ago I fitted new plugs, leads, cap and rotor as the car was refusing to start, turned out the cap and rotor had completely died.
