Anybody here help me out?? My car is acting up. Its throwing codes but I cant figure out how to fix it using the stock computer. 
It has the check engine light and it's idling a little rougher. I checked all fluids and everything is fine. Oil level is perfect. I talked to my buddy who has a z06 and he says when he races his car after the fifth or sixth time his check engine light will come and he has to run the stock computer test and reset the codes. I tried doing what he said but It didnt work. I couldnt bring up the screen to reset any codes.
Anybody know how to do this or give me a web page to that can explain it??

What codes are you getting? You can get the codes by the following.
The IPC display, the 20-character, vacuum florescent screen above the steering column that says "Corvette by Chevrolet" every time you turn on the key is a powerful device.
DIY Service Techs are going to be most interested in the LPG’s ability to show diagnostic trouble codes (DTC) for all the modules that transmit them.
The "diagnostic display" mode is entered with the following Procedure: Page 8-500
1) Turn on the ignition but don't start the engine.
2) Press the "reset" button to turn off any warning messages
3) Press and hold "options" and
4) While holding "options", press "fuel" four times within a 10-Second period.
Initially, the on-board diagnostics go into the "automatic" mode, which shows each module's DTCs in a
pre-set sequence: (Page No. are for the GM Service Manual)
10 PCNI Powertrain Control Module page 6-357 - 6-361
28 TCS Traction Control system ABS on page 5-86
?? RTD Real Time damping page 3-136
40 BCM Body Control Module page 8-405 LTD Page 8-727
60 [PC instrument Pane! Cluster page 8-508
80 radio page 8-213
99 FIVAC Heater Vent-Air Conditioning page 1-118
A0 LDCM Left Door Control module page 8-904 to 8-951
Al RDCM Right Door Control Module page 8-904 to 8-951
AC SCM Seat Control module page 8-1064-8-1082
B0 RFA Remote Function Actuation page 8-676
PM your Email Addy and I will send the Word doc. that includes the code list and faults.

That link will take you to a document that explains it all in full as well as an index to decode the codes. Good luck.

I had a bad plug and wire. I needed a tune up. Car has probably never had one and it has 31k miles on it. It has seen the track more and a few more races. The idle wasnt very rough. Just a little bit more than normal. All is fixed and its back to its normal stock looking sounding docile self until full throttle. Thanks for your help Rojo.
I just bought stock replacements that cost me about $15 bucks total in parts and I put them on myself. I plan on doing a small tune up after x mas with all new plugs and wires and replace them with better parts. LS1 Tech Stories
