Had a problem with my z mis firing only when its warmed up though

 

well changed the plugs and checked the ecu and its coming up with a problem in the ignition signal circuit?

 

my first though is that its leaving the choke open since it only does it when its warmed up

 

any ideas before i try and repair or replace the PTU/harness

    Doubt you have a sticking choke matey, check your connections first, they are usually the problem, go round and clean them all as they are usually dirty and its the cheapest easiest place to start.
