Mis-fire?

Recommended Posts

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?

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
