SES light, rough running 97 silvarado
I got the flashing SES light on my 97 silvardao this morning. It's has the 5.7 litre vortec with about 66,000 miles. I could feel the engine running a little rough on the expressway this morning and I had the flasing SES light. On the way have this evening, the SES light was on steady the the engine was running smooth. Anybody have any ideas?

You might want to check the o2 sensor as with time they do go bad and trip the SES light.

The guy's at Autozone checked the code and it came back as a "misfire on cylinder 7". I picked up new plugs, wires, cap and rotor. The truck has 66,000 miles, so it is probably due for a tune up. Anybody have any other ideas?
