cylinder not firing

I've got an 05 gto that I think has a cylinder not firing all I know is as I was traveling down the highway the entire car began to shake as I shifted into 6th gear and the engine light began to blink, after coming to a stop it began to backfire after reving it high than 1900. Can anyone shed somme light? Give me any suggestions? Thanks!

Make teh secks on your OBDII port with a scanner and find out what's up. A blinking CEL ought to have stored a code.

Start simple and check your plugs and wires, and have it scanned by Autozone.

Sounds like a good idea. Do you have any other possible ideas what this might be? I'm just concerned because not only did it back fire on me every time i revved it higher than 1900 but as I was driving through the city to get to my garage it would act really jumpy and then kind of sluggish.

If it's only one dead cylinder it's usually injector, plug, wire, or coil. Find out how many cylinders are missing and we'll go from there.

<-- Guess which ones quicker?.....Nope! Not even close.

Would you care to share what it was just in case it happens to someone else?
