so this misfire continues , today I swapped out all the injectors cleaned and fitted the best ones I had out of the 12 I have got still the same , one thing im noticing is the car runs good for a while then goes bad after a 15minute drive with booting it , noticed this the most the other day when I was clearly running with bad misfire , swapped coils to pin point but still the same , pulled off injector plugs to try and pin point but its not as bad as a full dead injector and couldn't tell a difference between cylinders was still worse when getting boost, unplugged the battery for half hour then it was running with hardly a misfire .
starting to think that the aem fic is playing up as I don't get a error code from the stock ecu.
think it might be time to get it to somewhere with a rolling road to test this fault
