Hello, I see that this TSB applies to 10-12 and not an 08 like mine. The issue I am having is that after truck is warmed up, say I drive 10 minutes to store. I turn it off, and then come back 30 minutes later to go home.
With the AC on and leaving the parking lot, If I am waiting to leave the exit/entrance, once I turn the steering wheel, I can feel the idle getting rough. It is like back in the old days where a carburetor needs to be "cleared out" by revving it a bit. Will the idle learn fix this? It is idling around 550 RPM at this point when its rough. It dissipates for the most part once I get moving, afterwards.

Thanks,
David

i also too have a 2008 frontier and mine does the same
thing. i just got mine last week so im new to the
problem. from factory once warmed idle should be at
650rmps. or give or take 50. so if its around that
range then thats where it should be. but due to being
that low the engine has a hard time keeping it self
running smooth at idle. if you are at a stop light and
put your foot on the brake and bring the idle up to
around 750 or so it is alot less worse. so the answer
is turning your idle up. nissan knows about the issue
and will turn it up for you but at the cost of there
hourly rate. or what im still looking into is i heard
people using the bullydog tuner or the superchip
cortex to turn the idle up. i have called both
companies and they have said that they can not. so if
anyone has done it that way i would like to know how.
