Well did a eng rebuild everything except crank came out did everything per ls1 how to directions, now I'm getting cam sensor low voltage code, along with my tach coming in and out while driving and start up is cranking for about 10 seconds sometimes and then it starting, horrible gas mileage.

So I replaced the cam sensor, thought it worked but after driving the problem is back with the same symptoms, I think it's now a wire problem or ground or another plug I missed when putting everything back together, how do I figure out my problem now?
