Need help with error codes

[40thGT]

My ses light came on a couple days ago and started flashing. Nothing seemed wrong with the car...I ran it alittle and then the next day the ses light never came on. While driving on the interstate today it came on steady so I drove to the nearest autozone and got the following results...P0300, P0303, P0305, P0306. Multiple misfires detected, and also misfires in cylinders 1, 3, 5. Yet I do not feel anything. I have done no mods in the past couple of months. I found some threads related but nothing specific. Tonight I disconnected the battery to reset the computer, propably put about 10 miles on it...no prob. Then while showing off and smoking a sidewalk of ladies it seemed to miss at about 5000rpm...but the light never came on? Any suggestions or should I just take it to the ever so trustworthy dealer?

Could be couple of things mainly your spark plugs and coil on plugs. If you got a warranty take it to the dealer.

you don't feel any misfires. stumbling anything? with those codes that car should barley be running.


i would take a good look at the crank sensor and the tone wheel. there are a few other things it could be too. but start there.
