Just changed plugs and timeing chains, gone about 1000 miles now i'm getting a slight miss occasionally, not consistantly, with my '06 STS v-6 with 113,000 miles on it, no codes comeing up, leaving for FLA from ohio in the morning any suggestions on this.

Is the engine oil the proper GM grade, viscosity & level?
