I recently aquired a 2002 z06 and I was seeing what it would do today, I must say I am not very impressed. It didnt feel like I thought it would, I'm thinking it might be skipping when i mash on it. I didnt really notice anything wierd untill 4th gear around 110 or so, it sounded like the car was sputtering and skipping. The car has 24k miles on it so a plug shouldnt be bad right? No abnormal sounds from the engine. I have driven the car be4 in the past and it seemed much faster. Only mods are CAI and programer.

I might change the plugs on my day off.

should run some octane booster or something through it?

Any help will be GREATLY appreciated.

I have an 02 Z06 and my car does not do that. You might want to get the car checked out. Maybe it needs a good tune...

It definitely has a problem, that car should give you nothing but thrills.

You "acquired" it? What is the cars history?

no codes, I didn't notice it untill forth gear, I havent run it really since then.
My father bought himself a 2003 z06 with some mods and im buying the 2002 he had. The thing is, It has never done this when i drove it untill last night.

Has to be something wrong. 110 mph is nothing for a C5Z06. Just a thought, but could you have been hitting the rev limiter in 4th gear? I am guessing that would be about the time for a 5th gear shift, but I will defer to the far more knowledgeble members here. I know I about run out of 5th gear at 150mph + or -

Is it showing any codes? Does the car do this at the same rpm in any other gear? Is it speed related or engine rpm related?
Im having a similar issue now. Mine is RPM related, specifically around the 4-5K range

Any help/advice welcomed!!!
