E3 spark plugs
Just put in 8 new E3 spark plug(E3.62). My check engine light started to blink then it stayed on steady. I really don't know that much about trucks or cars. I would love to trick out my truck, but so far not having good luck. The plugs are the first thing I did. I have an GMC 2003 Ext cab 4.8L V8 1500. I need some help; change the plugs and/or take it somewhere to have it fixed.
HELP OUT THE NEW GUY!!!

I've seen both positive and negative reports on the E3's. Are you sure you got the plug wires snapped back up correctly and didn't crack the ceramic on any of the plugs? Either of these will cause misfires, which will cause the check engine light to flash initially and to go to constant on if the misfires continue.
