[QUOTE="trevor72, post: 46649"] Hmm... well I;m pretty sure that if there wasn't enough fuel getting there, then the plugs wouldn't be sooty black. You are bang on exactly the same wavelength that I was thinking about, the plugs should be light brown when runnng temp is reached. I am very curious about what this "CARB SOLENOID VALVE" is. Is there any way you could expand on this? It seems possible that this or another valve may be staying open causing the plugs to foul when the engine warms and no longer required an enrichened mixture. Now as for ECC = not sure. My '90 red k10 had a computer under the seat, but this one doesn't seem to. This is the one year only canadian made '87 micra. It does have a small 'thing' under the driver's seet, but IIRC it is called the engine revolution control unit or something like that. I did test for contenuity there at some point a very long time ago. OK, there are 3 sets of wire leading to the carb. ( BTW this is a new carb, the original one stopped flowing fuel for some reason.) One is the anti-deiseling solenoid and the car will not run with it unpluged, that's working. the other two seem to have no effect. I remember testing the others as they didn't "click" as did the anti-dieseling solenoid, but again if I recall correctly they had power at the connection. I can check again tho. I'm definately interested to find out what you've got on this "CARB SOLENOID VALVE", and which one you are describing as your problem. Have you got your's sorted? Thanks. Trevor [/QUOTE]
