CHEVY CHECK ENGINE LIGHT FLASHING

2003 Chevrolet Tahoe

Engine Performance problem
2003 Chevy Tahoe V8 Two Wheel Drive Automatic 133000 miles

My check engine light flashes. Once in a while it will stay lit and pulls up a random misfire. It has no power and when you give it the gas the check engine light flashes. Sometimes for a while, sometimes for just a few flashes. What could it be?

If the code indicates a misfire, when was the last tune up? ALso, have you checked to make sure the catylatic converter isn't plugging?

The plugs and wires were changed about 3 months ago. Could it be a bad plug?

Yes, you could have a bad plug, wire. Also, make sure the converter isn't plugged.
