This has been a minor issue ever since I put in my cam in last year (240s duration 111 lsa) - 2001 C5 Corvette. The idle lope is pretty choppy, and this is known for setting off a false misfire detection.

I have the P0300 code set to "not reported" on C6001, and "no MIL" on C6002.

During periods of long idling only, the MIL flashes. No codes are reported (through the dash DIC) when this occurs, so I assume it's still the misfire detection having some effect. If I rev it up a little bit over idle so it smooths out, the MIL light goes out.

It doesn't bother me so much, as I know what it is...but anyone who looks inside the car while it's idling inevitably asks me about it.

I looked at the misfire parameters and tables. If I set C6602 to a high enough temp that misfire would never be tested for, will this work, or would it be unwise to do so?

Any other suggestions/possibilities?

Also, if it could be something other than a misfire detection setting this off...why can't I pull up a code for it?


Thanks,
Tom
