I have a 2000 firebird that we put a 5.3 with 799 heads and comp cam that is 224/228@ .050, used a aftermarket harness on the motor and keep getting a cam sensor low input and high input. Not at same times they keep switch around. Car starts good sometimes and not the other times ( caught through exaust) and very fat. Kinda stumped we checked and getting 12v and ground at sensor help would be appreciate. Also it's a 411 computer and x24 wheel
Thanks
