So I began to have an issue on my 09 Cobalt SS where I'm randomly losing all boost and power I build up while driving. It bogs down and hardly accelerates even when wot. After a while a CEL popped up giving me "P0243- Powertrain Turbo/Super Charger Wastegate Solenoid A" Anyone know the part number for that solenoid? I called the dealer but they wanted me to bring it in and pay 115$ just to tell me what I already know.
