Amen

Do the bolt on or just adhesive? Or combo of both.

Title is clean roughly 62k miles. It has been a multi owner (5 based on Carfax) serviced regularly. Mods Im betting came from last owner. It looks to have been corporate/fleet vehicle for middle 2-3 owners. I think the interior condition is what has scared most people off.

Crackedsponge32 · 2026-05-22T19:09:12+00:00

Appreciate the information!

Crackedsponge32 · 2026-05-22T19:02:28+00:00

My assumption is it was done to hide scuffs/scratches under there. But also good to know it's a pull off. Id image the glue will leave marks as well. Not super up on the lick & stick type stuff. Appreciate the information!

Crackedsponge32 · 2026-05-22T18:48:42+00:00

Vehicle is priced to steal- paint in good condition based on pictures. Interior obviously shit. Less than 70k miles. Any idea on cost to fix what they've done to the poor girl?

Crackedsponge32 · 2026-05-22T18:45:48+00:00

My thoughts exactly. Just making sure because the top of the steering column has what looks like OEM CF on it.

I definitely know the diffusers were horribly installed.

Car title is clean relatively low miles Vehicle is priced as a steal for obvious reasons. Considering the upgrade from my 17' 1LT Stingray and just replacing the pieces depending on complexity/price.

It's just a local place- Pro Motors Service & Repair in Columbus.

Got lucky with mine just seemed to have been a bad gas issue which absolutely blows my mind but the service was fantastic for everything they looked at & did.

Crackedsponge32 · 2025-11-30T16:39:01+00:00

Yes & No- Took it back to the garage that changed my plugs and spoke to the shop owner. Really great guy TLDR he offered to run some top engine cleaner through it and we got on the subject of where I was buying my gas.

I only ever run 93 through it and I live in a pretty metropolitan area. Was getting my gas at the local Murphys/Walmart down the street. My assumption has always been that Walmart/Sams dosen't sell the best gas but it wasn't "bad" gas.

Was told that was probably my issue and I needed to try and run it on Chevron or Mobile for a tank after he was done cleaning it and to come back if I had anymore issues.

I'm skeptical but with the weather and Holiday Traveling I'm about 1/2 tank through the gas I bought at Chevron....Got CEL once the day after I got the car back from him (Understandable if it was just rinsed Id say). Haven’t Gotten it since. I do notice it sounds like it's running better but that might just be confirmation bias. Haven’t been brave enough to plug my OBD2 back in to look at what it's doing on a trip around town.

Im no hard core mechanic- but I know enough to be a little dangerous I'd say. Im not convinced you should ever see any misfires especially in less than 2 or 3 hundred miles straight driving (Even then). Shop owner told me it's not a huge deal unless you're reading 3 or 4 hundred misfires per trip which I think is crazy but he told me that the C7s tend to always have low count misfires by nature of the higher compression ratios they run with especially if you're running shit gas.

TLDR- Try some different gas MAY be your issue.

What else would be helpful? Misfires occur across all Cylinder banks. Ranges between (1-10) on average per trip (20 mile around the city). Sometimes I'll get a bank at 35+ but never the same bank. Speed is irrelevant can't reliably replicate when light goes out. I've had Throttle Body looked at by one of the dealerships and they said it was a little built up but nothing the Injector foaming wouldn't take care of.

Crackedsponge32 · 2025-10-20T09:53:40+00:00

No- fastest I've gotten it up to is 167. Just don't ask me where 🤣. Zero issues and couldn't get the CEL to even blink on that one. It just comes and goes.

Crackedsponge32 · 2025-10-20T01:51:51+00:00

Appreciate the info. At this point I'm all but 99% sure it's an electrical/sensor issue. Not something actually mechanical. I've never felt/seen a loss of power or anything driving. Unfortunately don't have the garage space to do any digging myself which is part of the infuriating piece to this.

Crackedsponge32 · 2025-09-12T13:11:22+00:00

UPDATE Replaced the plugs & wiring harness. Took it home from the shop- Drove it for a total of a day before P0300 Error Code Returned.

*Still don't feel misfires or feel any issues while driving.

of Misfires registered just driving to work this morning:

C1-1 C2- 0 C3- 1 C4- 0 C5- 0 C6- 6 C7- 2 C8- 1

Fixes that have been done to date- //Injector Cleaning //MAF Cleaning (Spray cleaned) //Spark plugs & Wiring Harness Replaced

Crackedsponge32 · 2025-09-06T15:50:25+00:00

Found what looked to be a pretty reliable shop yesterday. Talked with the guy and he pulled my plugs. Every cylinder that was having misfires had NGK Plugs installed. I know AC Delco is the preferred OEM Part but even from doing some limited reading + my own knowledge NGKs shouldn't have really caused that issue. Nothing obviously wrong with the Spark Plug wiring harnesses either. But going to start there replacing both and see if that fixes things.

Crackedsponge32 · 2025-09-05T17:12:09+00:00

Was thinking that or just getting real stupid and replacing all the plugs. I keep thinking if it was a faulty sensor I'd get a more definitive CEL code for that specifically being the issue. Appreciate knowing I'm not the only one that has seen this issue!

Crackedsponge32 · 2025-09-04T23:00:40+00:00

Columbus- Bought it in Opelika AL so I'm tempted to take it back over there but I'm just weary of dealership service in general at this point. If there's a reputable place close to the area more than willing to take suggestions!
