New 2016 Z06 Owner - With some issues
Hey guys, just wanted to introduce myself and talk about an issue a lot of people seem to have, but I'm not sure if mine may be a little different.
I just bought this 2016 Z06 with 6k miles on it - White on Black rims and it looks and sounds amazing. Really love the look of this car.
This is my first Corvette, I'm coming from an M4. The amount of power is kind of insane and I just love the power delivery. I bought the M7 because it's just more fun to row your own gears.
So my issue occurred within the first week. I had driven back and forth to work which was roughly an hour total, picked up my gf to go grab some lunch and I go to step on it in 2nd and I literally get less than half the power. OK, weird, maybe traction control kicked in. Try it again in all gears, I just have NO power.
I get a little annoyed, look at all the temps, my coolant is like 205, my oil is 200, trans only like 120. So what gives? I cruise on the highway a bit temps dip below 200 and then I get most of my power back but not all of it. Floor it a few more times and it just slows down so much its embarrassing, the rest of the ride was just all noise, no go.
I let the car sit for a few hours, let it get warmed up, try again and back to full power. So, I knew about the issue with overheating, I've gone through that ridiculously long thread and my issue seems to be different. I'm not seeing high temps for anything, and even though I am pushing it, I'm still only on the street, and it's only 50* outside!
This was a CPO car from a dealer, should I be bringing it back already?

Your issue sounds like it could be related to air being trapped in your intercooler. There is a GM procedure the dealer can perform to refill via a machine that minimizes air being trapped in the system. I would bring it to the dealer as they should know about this and how to fix it.

my opinion is these c7’s are over complicated and finicky with displacement on demand, and an over protective ecm protecting the car from itself.
I know what the op is
saying. I have a brand new 2017 bought day after thanksgiving. I drove one warm day here in St. Louis in December around 60. Stopped for lunch for 30 minutes — after lunch took off on a highway on ramp and thought this thing is pretty amazing. Then after 20 minutes in light stop and go traffic with coolant temps at 195 and oil temps at 180 stood on it when the traffic cleared and I thought man this thing is a dog. I thought my old c4zr1 would blow the doors off this thing.

Air in the intercooler circuit causes the pump to cavitate. It has a built in failsafe to shut down for few minutes (can't remember how many, i think 3 minutes) before coming back online. You lose a lot of power while the pump is offline. This was the issue with one of the cars Randy Pobst was driving during the magazine tests.

I mean, I tried to use reason and it was above 1k and I didn’t put any load on it.
Aside from it being dumb slow. Sucks I’ll have to wait a while in order to actually experience this car.

purge air from the intercooler.
Check the trans and differential fluid. These cars have been known to be underfilled from the factory
get a street alignment. This will supposedly make tires last longer and the car will track straighter in full throttle.
There is also a know problem where these cars throw a p106 error and it pulls power.

There are a number of things that will pull power and not give much if any indication of a problem - bad gas causing knocking, a bad O2 sensor, a bad cat converter.
But one of the things is too much air in the CAC (Charge Air Coolant) or intercooler system. Take a look at this thread about the intercooler pump cavitating and causing an exactly 3 minute limp mode - and there are no lights, alert messages, overtemps, or any other indication of the problem:

Get a flashlight and open your hood - the intercooler reservoir is up in the very front right corner. Take a look at your intercooler reservoir - it should not have much more air in the top of it than the small bubbles you see in the picture below:
If you see something like in the picture below, then you have waaayyy too much air in your CAC system and you're very subject to intercooler pump caviatation and the 3 minute shutdown of the pump. You'll need to either have it vacuum filled, or you can do a procedure that's posted up in a video here on the forum. The pic below shows too much air:

M4 seems like it would be a nice car. I haven't driven one. Did you trade it on the vette?

Typical reply from a Bimmer guy... "first CHEVY I have owned" .... Yeah you wanna know how much crap goes wrong with BMW's, P cars etc..Your first late model Corvette so you don't know the legend of Corvette and it's history highly. It's racing titles etc etc...
I know you are new and the car is exciting to drive and it is frustrating...it's a small thing and you will forget about it once its rectified. It's a Corvette Z06... not really a Chevy anymore. JFYO.
I agree there should be Corvette and Cadillac dealerships with upscale sales reps and top notch mechanics with a niche for those cars ONLY.

CAT OVERTEMP that'd be my guess. i wonder if whoever had the car before you had a tune in it and toasted the cats? or plugs are shot? try to record the boost gauge when you get on it again and post it up here. if cats are toast the boost should spike noticeably. Dealer can run it for codes. sucks. whoever traded it in knew about it that's almost a certainty.
on sport cluster display, edit your gauges, make one or both (left and right) read "HP" and then get on it record that and post it. it's a very crude measurement but if what you're saying is legit it will indicate on that gauge.
