About 2-weeks ago I changed my spark plugs (w/ Platium+4) and wires. Then yesterday, I went down to AutoZone the other day because my Check Engine light was on. The OBD machine said multi cylinder misfire. Today I was messing with my spark plug wires and since I messed with them my engine stutters. Does anyone know the cylinder locations? Is there anything you can think of that may be the problem? Thanks!

check you owners manual for the proper firing order, however you may have some bad plugs or wires, or not connected good. i have had bad injectors send this same code.

the front plugs are 246, the rears are 135 left to right. The coils should have numbers on them, but if not from the left 523641. GM's do not run well with Bosch plugs, infact they don't run well with anything but AC Delco Plugs
