2005 STS V6, CEL came on last week while I was driving. Stop by O'Reilly and how the codes scanned: P0430, P0306, & P0206.
Since then I have had the oil changed, new spark plugs, new ignition coil for 6, intake gasket replaced and fuel injector #6 replaced. My car is still running rough and the link is blinking off/on more. Any advice? Cadillac mechanic/tech in Dallas,TX? Should I take it in to the dealership?

Thanks

Are you driving it while its blinking?

IIRC a blinking CEL is usually indicative of bad misfiring occurring while it is flashing.

A blinking CEL means there is a critical problem with an element of the emissions control system that is currently causing severe damage. Bad misfires grunt the CATs in short order and may get hot enough to set the car on fire.

Yes, the light blinked while I was driving. I think I need to get it towed to the dealership to prevent any more problems......

Probably another bad coil pack.
