SYS Signal on Display
I was running my A.C. and I took off fast.,Suddenly my car began Missing really bad. I cut the A.C and car off. When i restarted the car my SYS was displaying on the digital display. Then the car began to run normal. Has anyone experienced this? What is that? Is this a warning of something going bad? The car has 67,000 miles and it's a 1994 LT1 Corvette with all the options

Re: SYS Signal on Display (C4CAT)
When the SYS is on the display, does the rev limiter kick in at 3000rpm? Use a paper clip to run the codes and see what pops up. I am not sure if it will work on a '94 but on my '92 if you short positions A and G on the diagnostic plug, the codes will come up on the dash.
