Recently replaced plugs and wires in 2004 Chevy Silverado Z71. It now idles very rough almost to the point of stalling and misfiring. I found a forum somewhere that mentioned wrong plugs but now can't find it to show the hubby. Any help is appreciated! Love these forums!

I have a 2012 silverado and my check engine light keeps coming off and on. The codes read are c0900- device 1 voltage high(history) c0899- device 1 voltage low(history) p0300- multiple misfire detected (History Mil) p0301- cylinder 1 misfire detected (confirmed) there is a slight rough idle on the truck, and I think that my gas mileage has decreased slightly Does anyone have any idea what my problem could be before I take it to a shop, or start replacing parts
