I ran into the same issue after my second track day. I initially thought that I had bad fuel and since I couldn't reset my ECM (apparently not easy task on these cars), I was under the impression that the ECM cannot recover itself from the bad/low octane map or pulling timing or something (as it did with previous Gen Camaros).

I've scheduled an appointment with my dealer for this Wednesday to do that. It's also a bit hard to replicate the issue on rainy, cold days since it requires a WOT and can only be done (safely) in traffic on 2nd gear.

I was scratching my head because it happened to a 17 Camaro SS owner, a brand new 1LE at the dealer showroom(!), to my 17 1LE and a 17 ZL1 owner. I would understand the SS cars but ZL1 has a completely different motor and a tune of course. Forum member "geaux_tigerss" says that the dealer replaced the camshaft solenoid and ECM but still didn't fix the issue . It turns out that the A/C belt -under high load- was rubbing against the wiring harness right below it, and stripping two wires and causing that surging issue at around 5500 RPM. It didn't reach to a point where it displays a CEL in my experience but he had both CEL and the issue was existent all the time.

I checked mine and as expected I was dealing with the same exact issue. I took some pictures showing how it's stripped. It looks like a manufacturing defect and somehow they didn't pay attention to that clearance between the wiring harness and the A/C belt. I would be surprised if the clearance is different on other cars unless they changed the method of putting the wiring harnesses all together. I would highly advise to check yours and if you don't see any rubbing/stripped wire, consider yourself lucky and simply put a zip tie to make some space between those two (wires and A/C belt above it)

I put the below pieces aside for an easy access:


Notice the two completely stripped wires touching each other in the below picture.. right next to the purple wire:



I used some electrical tape to insulate those two wires (simply pushed some tape with a thin, flathead in between) then wrap around it with another electrical tape and zip tied it with the connector wire so that it would pust it away from the belt and give some space.
Note: Needle nose pliers helps a lot if you have big hands like me

I took it for a quick ride to test it and the hesitation is gone now. Phew! what I relieve ..

Great thread here, would you be cool if I made a video to alert other Camaro friends, at least getting them to check their cars to see if they are seeing this issue? I'll of course give all credit to you and link back to this thread. Shoot me a DM if you're cool with it.

Geeze, that's a really crappy design. "Lets put some wiring harnesses right next to a moving belt driven system." Engineering skills. :/

I hope they issue a recall for you guys, even if its something as minor as adding a zip tie to move it slightly. Still, that must be kind of unnerving if it were to ever shift around, plus the general fact that if you ever needed the engine serviced, a mechanic could end up undoing the fix very easily.

I have to mention though there are so many owners with no issues but it's definitely worth checking

Thanks for the info

May just be the angle, but it looks closer than an inch? (the blue and yellow wires and such)

A video would be great fellas...as it would be able to show exactly where this harness is from multiple views. Some may need that...

Thanks, I'll check mine tonight!

Looks like 3 wires:
Purple, Blue, and yellow/black
That would work for a Hall effect sensor which has:
1) Signal
2) Signal ground
3) reference voltage

Well my car was throwing codes P0011, and P2088. Took it to the dealer to read the codes, then sent pics of them to @slick3. He sent me this thread and what do you know....my belt was rubbing as well. Currently trying to contact the dealer to get a resolution in place.

P0011 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

P2088 - "A" Camshaft Position Actuator Control Circuit Low Bank 1

Should've stuck with my first guess!

FWIW to this thread I checked my 16 SS A8 and this wire is nowhere near the belt.

Yep lol. The service advisor started reading the codes and i was like oh no (my G8 had some electrical issues that forced me to trade the car in). Thankfully I was able to assess the real cause. They probably would've replaced the solenoid (p2088) and then tried to figure out what else was wrong.

Well... guess I know what I'm doing tonight

[glamcem]

all good info, thanks everyone

I wish I didn't forget to add a poll to the OP so we would be able to tell how frequent is this issue.
