    5.7 starting issues

    So replaced cam sensor and put new cap and rotor in "but old looked new" and it fired right up. Not sure if it was the cam sensor or it just started as a fluke but I will take it. Hopefully no more issues. Is there anyway to test the old cam sensor now that is out, naybe with a multi meter?

    So I found the decal and if I am reading right ir is 44oz for my Tukon with rear A/C. I will replace the dryer as it has never been changed before. Should I get 3 cans with the dye or just need 1 with dye and 2 without? Also is one brand of refrigerant better then another?
