Been trying to trace this problem down for some time. Car in stock form is fine with zero misfires and runs great.
I installed FIC1200 injectors and I was getting misfires across the board, contacted FIC, sent the injectors into them. They cleaned, and flow tested them. Found a bad injector and replaced it.
Received the new injectors and installed them with tune for injectors only (with data supplied from FIC, and FIC verified tune was correct for injectors), and car misfires at idle. only Cyl4 and cyl6 (misfire counts increases fast in Forscan, 300+ in a matter of 10-15seconds). Car idled pretty rough.
Thinking it was injector related, I moved the injectors around, misfire did not follow. Put stock injectors and tune back, car runs fine.
Leak down and compression tests have all been done over the winter - engine itself checks out fine. Spark plugs were new about a month ago (drove car around stock for about 3000miles, and I can put stock injectors back in with zero issues).
What am I missing?
