Hi I have been using my mothers 1996 sierra 1/2 ton 4x4 and it has a newer goodwrench crate 5.7 in it, and it need new o2 censors but it only hicups a little bit on low side of RPMs . But I had some code that came out on a hand held diagnostic that when looked up said camshaft to crankshaft coralation is not in sync??? what is this mean and how do I fix it. Still runs ok.
