Turbo ITR throwing missfire code
Throwing code 71, 72, 73, 74 (misfire in cylinder 1,2,3,4).
Stock B18C5
350 cc injectors
Split Second fuel piggyback
High flow pump
Garret GT25R
7 lbs boost
94 octane
Car was extensively tuned on the dyno.
The car runs great, and idles well. But it throws the codes during warm up idle occasionally. Like the care will run great for a few times, and then out of the blue it will throw the codes next time I start it cold. The plugs look good. My mechanic and I are stumped, anyone with any input?

Re: Turbo ITR throwing missfire code (Dr Pooface)
My car does the same thing, only in winter. I'm told that colder heat range plugs can misfire until they warm up.
As long as it doesn't misfire after it's warmed up, I don't worry about it.
