CONSULTATION

Hello friends, I need information about the ECOTEC 2.0 16V engine preheating system. (My car is an astra gls, equipped with that engine). The reason for Dicah consults, is that 2 days ago, it has begun to have delays for starting. Locate where you have preheated spark plugs, but I don't want to harm anything until you know how to remove them, try them and the timer too. This material would greatly add. greetings.-
