Helpppp... Long story short ... Possible blown head gasket... Been sitting after that was the diagnosis my nephew came up with due to white smoke from exhaust but only when revved to high rpm... I cleaned throttle body entirely including valves n gaskets and tps... Put back on n back together n rough idling... Will stall if just in neutral idling ... Havent driven or turned on for about 3 months so im down today she starts up n sounds good no smoke look at plugs and..... I see this shit
