Engine Performance problem
2001 Chevy Silverado V8 Four Wheel Drive Automatic 119, 00 miles

I just changed the spakr plugs, and wires and changed the air filter and oil yesterday. Went out today to start it up and the engine is idiling really rough. Usually idles at 700 rpm, and this morning, it would spike at 1,000 and then surge and try to find a idle speed and then it would die, Any help?

Hello, did you have this problem before you worked on it? Maybe you knocked a wire/connector loose or a vacuum line? Can you check for codes?

I did ot have the problem prior to Saturday. I will look everything over again, but I did not see anything that was loose. I hooked a code reader up to it and it said pass. So I do not know what the problem is.
