Unfortunately the inconsistent acceleration is back
When I'm driving at a lower speed and accelerate quickly, 1 or 2 gear kick down, I notice that there is a lot of power oscillation, not a good clean upward power curve. It's almost like it's hitting a rev limiter, but not quite that harsh. I'm beginning to wonder if it might be a fuel delivery problem.
So I think I have your problem. did you ever find a solution to this? the dealer has replaced the following
Turbo Inlet Hoses
Stage one Kit
Mass Air Flow Sensor
a host of other attempts to repair it
The problem is worse with the Stage One Kit
Their final solution was to remove the Calibration and leave the Stage Kit. The car is getting the following codes
P1101 Intake Air Performance
P0101 Mass Air Flow Circuit A
and Since I got it back
and a couple of others all being CAN-Bus Communication Failures.
The Manufacture is basically disclaiming the issues and literally telling me that the car is normal and this is how it is suppose to be.
I have spoken to everyone from insiders that I am acquainted with, The man who released the GM performance parts Stage One Kit, The District rep for Jacksonville Tim Dobbs, The Regional Rep David Fortunato, The liaison to The Executive department Quentin..... Every single one of them pushes it off and to the next person above or below and blames everyone else.
Hilton Head Buick GM kicked me out after the 5th attempt of repair, Critz Buick GMC kicked me out telling me they can't fix my car.
I'm done.... They can keep it. I only have 28k and I bought this in November of 2015. The car has been in and out of the shop for a total of 8 months of being there in 11 months.
They have also replaced
Right front axles
Both rear wheel bearings
Right rear window quarter
And Critz Buick caused a ton of damage to my car. what a joke....
