C5 Engine check light??

[BLUETHUNDER]

Just had a good weekend with the Vette taking in the south coast.This morning i noticed the check engine light appeared.There is no difference in engine performance or fuel consumption.I also checked the make sure that the leads going to the lambda,s were still connected and i have,nt got rattly cats.The car is going in to Ian Goss on wednesday for him to check on the diagnostics.Just wondered in advance if anyone else had suffered this and what to expect.

Thanks for any info given.

Mark.

Yep, I have it when I go full throttle for an extended period of time. Buy a very cheap OBDII scanner and it will tell you.

Mine was 02 sensors but its not running lean (checked at Surrey Rolling Road). If you are London way you can borrow my scanner.

The Goss Guru will sought it out! I need a new 02 sensor when my light came on before!
