RobAce Posted August 2, 2018 Share Posted August 2, 2018 I have got a mis fire on the front cylinder, not spark plug or cool pack, after running the spark plug comes out sooty and dry. I'm running a t-61 with a e-manage ultimate I think either dodgy injector or no signal going to the injector Anyone got any ideas or ways of diagnosing it?

mellonman Posted August 3, 2018 Share Posted August 3, 2018 You did check the coil clip right ? Also you could unplug the injector and see if it's the same state . Then plug a spare / another one in and see if it's spraying ( into a bottle mind last thing you want is petrol spraying everywhere). How many chanels does the ultimate have 6 or 8 if it has 8 then you could wire no1 signals to 7 or 8 . If you think ecu issue But as it's after market it might be best to go over the 1 cylinder wiring as this could be ignition or injector signal related Link to comment Share on other sites More sharing options...

RobAce Posted October 22, 2018 Author Share Posted October 22, 2018 So finally got round to doing some more work on my mis-fire Thought I would swop injector 1 and 2 around, if if the fault moved, did this and developed mis fire on 4 and 3 as well, car ran for a while, went out and now won't start Link to comment Share on other sites More sharing options...
