2005 Jimmy starts but then immediately dies if I do not give it gas.
I have a 2005 GMC Jimmy 4.3 standard, when I start it runs and then dies immediately if I don’t give it gas, this issue is not all the time but enough to be a bother. If I do use the gas method to keep it running half the time I gotta throw it in neutral at red lights to keep feeding it gas at an idle and the other half of the time it rectifies itself. The engine is throwing a code for an O2 sensor but has been long before this issue started and other then that no other codes. I need some advice on where to start or what you think could cause this, it dosnt seem to be temp related because it will happen in cold and hot conditions. It really seems to be at random, some days it’s fine and others not. HELP!!!
