5th gear hesitation

Having about the best time you can have while sweating buckets in oppressive heat here at Summit Point. Car is running great except when I'm shifting at redline from 4th to 5th. I'm getting a few seconds of hesitation in 5th gear. Could that be plugs? If plugs, any reason it's only happening in 5th gear on the front straight?

TIA,

SJ

See if there are any codes. I had the same hesitation but for most gears when i get one it. if normal smooth driving, it has no problem at all. I had a cylinder 6 misfire code, i cleared it and it hasn't come back yet.

Im going to look into spark plugs first, if still has the hesitation, i think im going to change just the no.6 cylinder ignition coil.

No misfire or ignition coil codes. I've got a DMTL leak which as I understand it is an emissions issue and might need replacing.

Coils were replaced less than a year ago. Plugs are probably due for replacing. Stupid me did not bring my spark plug socket to the track. Looks like plugs will be an early morning adventure.

Thanks!

speaking of that "increased emission" message, i did have that with the CEL which is cylinder 6 misfire. So is it my spark plugs or ignition coil or DMTL?

But i should start with spark plugs first right?

Spark plugs are cheaper. Coils are out of stock now except at the dealer so if you can wait a few months you would pay a lot less.

Do you have any sort of telemetry or data logger? Seems odd that you'd only get the hesitation in 5th gear.

Mystery solved. My clutch was going and it's completely burnt up now. It let go during my last session this afternoon. Surprised it lasted 11 yrs, the last four of which were supercharged. Calling the shop in the morning.

That's why the clutch never dawned on me but will hopefully know more as soon as I can get the car to the shop. Oh well, it's still in one piece.

I love how people come back and explain what the issue is. Thank you and best of luck on the the new clutch. Do you plan on going OEM or Aftermarket?

Since I'm supercharged and it's a track only vehicle I'll probably go with a heavy duty aftermarket one but will discuss with the shop to get the pros/cons of each.
