My rough idle issue after A2A install
I have idle surge between 13.5 and 15.5. this only happened after mechanic installed A2A kit I got second hand in Tampa, I doubled checked everything and it was in good condition. He said its normal to have idle surge since it has a bov but doesn't make sense since its before the maf lol
car 370z - has stillen sc , test pipes & catback exhaust, 9psi upgrade pulley, a2a kit , tial bov.
I placed the csv log in a zip file on here , I have a vid but its pretty much the same as the other one on the thread its just hunting and idle bounces as well. I sprayed the maf's just to make sure they were clean, as well as carb cleaner around the engine to check for leaks but no joy.. can it be the o2 sensors are black after the tune since it was kicking out black soot in the beginning ?... any ideas ?
