I have a 2004 SS/SC. Check engine light blinks, rough idle and acceleration, but only if the engine is warm at start. The engine runs fine from a cold start, no engine light, smooth idle and acceleration. The code references the fuel injector, but if the injector is bad, wouldn't the condition exist all the time, not just from a warm start? Help?!!!

 

did u scan ? what code you get ? do u have a live update scanner? I had the same problem it would change from 1-4-3 then back to 1. then radom miss-fire code cam up start with your plugs. I had Bosh and put in auto lights all gone car runs great

 

you find out what caused this? Having exact same problem but it's constant

 

I had the same problem as well on cylinder #4. It was the spark plug wire on mine. Good luck.
