my 05 is showing check engine so i go to auto zone to get code and it shows that B injector is showing circuit open...? won't go to local dc dealer as i am boycotting for not being straight about warranty service. used some power service kleener through and would like to clear code and see if that helped, but do i have to get dc to clear it or can i disconnect battery?

 

If the problem is no longer there it will go away after a set number of key cycles. I would pull the injector connectors apart and clean them up. Some dielectric grease couldn't hurt either.
Good luck

 

thanks , just don't want those knuckleheads,dc dealership, underneath my hood.another question anyone else had problems with dc on warranty work?
