Default 427 question, not sure where else to post

I need your help!
My 2013 427 was recently supercharged with the edelbrock SC. Everything ran great and never had a check engine light on for 2500 miles. That is until recently, lately from time to time my engine light will come on and my dash will show a "service traction control system". During this time the car is running rough and feels like its misfiring.
It will do this until I turn it off. Sometimes 5 minutes or hours between re-starting it is required to get the car to run right but when it is running right it is like nothing was ever wrong.
Has anyone seen this?

I would check your plugs and plug wires.

I'll do that, but if it was plugs / wires wouldn't it be running rough all the time? Most of the time it runs like a beast, only at times when the message pops up does it run rough.
At anyrate, its a great place to start, thanks.

First of all let me say it must be nice to have a new vert. I don't understand the S/C with a 11.1 compression ratio but what the heck. Its hard to determine if the wires are bad just by looking at them. There pretty fragile and even a cracked ceramic sheath on the inside can cause a misfire. Time to have a mech look at the car....hey...you can afford it.

Check for any stored codes. If you don't have a code reader, major chains like Autozone will check for you.

Or take it to the shop that did the install.

If the codes indicate a misfire on a particular plug, make sure that plug boot is fully seated.

Thanks.
I am a torque junkie. This is not my first vette or convertible. I sold a 2010 twin turbo GS to get this one. I love the 427 but as always I need more pull, I guess its a sickness. I'm only pushing 5lbs of boost and I dont have any plans to push more boost, although I will add headers, head work and a cam this next winter.
Yes, I't be at the service department this week. I hope it is something as simple as plugs / wires.

I would love to take it to the shop that did the install. Those guys are great but they are in Alabama and I am in NE PA. I'm just going to drop it off at the dealership and listen to them figure ways out to rip me off due to the supercharger.

Is there a local shop you can take it to?

One that might be willing to work with the shop in Alabama to help you with this matter.

I would be real leery of taking it to a dealership.

Isn't ECS in that neck of the woods?

It is probably not an install issue if it ran great for 2500 miles.

I would search for other reasons the Service Traction Control comes on.
I supposed a plug could have backed out, or a wire cracked.

More than likely it is an unrelated issue. A speed sensor can cause this. Wrong size/mismatched tires can cause this. Stainless steel brake lines can cause the sensor to act funny. Bad ground...etc etc.

The codes will lead you towards the issue.

They are. Thanks, I did not think of them. I'll see if they would be willing to help me out. I agree with you about the dealership. They could easily screw up things worst and or rape me in troubleshooting charges.

I hope your right. Like I said, 95% of the time its running like a beast with no issues and then,,,,,Bam the warning comes on and it goes to rough running. Very strange and frustrating.
The only mod at this point is the SC. I planned on more this winter but I'm just trying to enjoy it as is for now.

Since you report 'rough running' have the MAF checked.
IIRC rough running's a symptom of bad or ill-fitted MAF.

Is that something a owner without mechanical skills can check?

Might, be looking for loose connections and/or oil build-up. From what I've read over the years concerning MAFs, they're pretty delicate so it doesn't take much to cause one to act-up resulting in lousy (rough) performance.

OTOH if it IS a 'failing/bad' MAF, probably need expert's guidance as I do not know what diagnostic are invloved.

Thanks. I'll be careful but in the mean time, I am trying to line up ECS to see if they can look at it and maybe throw on some headers and retune.

That's your best course of action without a doubt. ECS will take care of you.

Perfect people, and time to check a MAF.
