2004 grand am 3.4l v6
Sudden rough idle and coolant everywhere under
the hood on the passenger side code says o2
sensors are bad and misfire on number 2 cylinder
where do i start?
You start by figuring out the coolant leak. If the engine got hot, there may be some big problems like a head gasket. Should do a compression test.
the coolant leak may have caused those other problems
Rowefast , beatupchevy the car never overheated
Well that is good, Just have to find the coolant leak. Maybe coolant spraying all over the place got some sensors wet and just need to dry out.
