He should be able to get the idle to go up (for testing to see if it makes any difference) by turning on everything while parked, turning on all the lights, heater on full blast, flashers, windshield wipers, defroster, heated seats, radio, etc and let it sit a few minutes the engine should automatically idle up to stage 2 or 3, it should do it automatically to make the alternator spin a little more because of the amp drain.His idle is a little low and the first thing tuners do is raise it 25-50 rpms. Low idle equals rough idle but as yet we cannot convince Dmitry to get BlackBear to tune it.
I have been watching carefully and documenting when I feel flutter - it happens even when truck sits idle in D or in P or N. In D it is more obvious. It happens during the day with almost no electrical load, with AC off, etc. and in the evening even if I push AC on with lights on. This morning on the cold start it was really skipping in 1200-1500 RPM, was really rough even with much elevated RPMs. It is dry and not humid. I am trying to drive to another dealer and drive 2020 Tahoe for 30 mins tomorrow and see if I am legally insane. Four dealers said that my truck is perfect. This is something to think about
I drove hard this weekend 360 miles round trip, kept it highway speed, accelerating and decelerating quickly.
I solved mine auto stop is working correctly for meDealer did check everything according to the work order:
Conclusion was - cannot reproduce any of my complaints. Truck is within GM specs. Advisor genuinely felt there is nothing that can do. Service manager was very accommodating and friendly but there is nothing that they can do.
- Engine mounts with picoscope
- Misfires cold and hot they said they see zero misfires on their equipment
- Injectors via afit test are all within 15% of each other
- Lugging/engine noise on the acceleration, not heard
I drove it for several hours since the pickup, absolutely no change, still misses as before, $06 monitor still shows misfires on cyl 7, cyl 6, cyl 4, cyl 3, cyl 1. Engine still makes noise on the acceleration up the hill in higher gear.
I think dealer did everything that they could without spending their own money. I respect them for that. I will take it on the longer drive this weekend and then if all the same - Nissan Armada is no longer as ugly as it was 3 months ago when I was buying this Yukon
