Right now it at tdc and even if I advance the timing it still gets red too.. I'm so lost right now.. I took it to the shop and they say that my timing was off by 10 degree.. They didn't say if it was too advance or too retard.. I bring it back to the shop and they can test it again.. To my knowledge that I think, I don't think the shop even touch my car. They charge me 300 and all my setting is still the same as I try to tune it..
