I'm getting the random missfire code coming up intermittently!

I've been reading all sorts from coil packs to boost leaks causing

 

My question to you guys is what sort of simple things could it be that i can I check myself before going balls deep into labour and diognostics

 

I have the Ecutek cable so can have a look on there but what tell tale signs should I look for ?

so had this code thrown up again today zero sighn of any bad running when it comes up. cars running fine it tends to be 10/15 mile into driving :surrender:

 

the only thing it dose do is on start up fires up then bogs down a touch to about 500rpm then picks up again and thats it fine from there on in :rant:

That will just be the rich mixture on start up (cold or hot start)

 

You can adjust the misfire numbers to stop this in the ECUTEK software.

 

All the Nismo 370Z used in the Sony Academy 2015 in the UK have now been swoped over onto EcuTek for the extra safety features we can tune in using racerom.
